It is known that the age of all employees are integers. It is known that the age of every employee in A is strictly less than the age of every employee in B, the age of every employee in B is strictly less than the age of every employee in C, ..., the age of every employee in G is strictly less than the age of every employee in H.
The highest possible age of an employee of company A is:

The Setup: Think of these companies as sorted C++ arrays. We need to maximize the final element of array A without throwing a logic error when it's compared to the very first element of array B. It's a strict inequality check, so we need to min-max the data to push Company A's ceiling as high as possible.
Step 1: Decode the median mechanics for Company B. Company B has 28 employees (an even number). The median age (30) is the average of the two middle elements. If we use standard 1-based math indexing, that's the 14th and 15th employees:
2b14+b15=30Step 2: Find the lowest possible starting age for Company B. To give array A the most room to scale up, we must push B's values as low as the rules allow. We can initialize the first 15 elements in B to exactly 30 without breaking the median requirement: b1=b2=⋯=b14=b15=30.
Thus, the absolute minimum age for the youngest employee in B is 30.
Step 3: Lock in Company A's max age. The constraint dictates that *every* employee in A must be strictly younger than *every* employee in B. In code terms, a32<b1. Since ages are strictly typed integers, if b1=30, the absolute maximum allowed for a32 is 29.
Step 4: Verify this doesn't break Company A's own median constraint. Company A has 32 employees with a median of 24. This requires the average of a16 and a17 to be 24. We can easily assign a16=24 and a17=24, which leaves plenty of capacity for elements a18 through a32 to cap out at 29. The backend logic runs with zero lag, and the max age holds up perfectly.
Final Answer: 29

The Setup: Every question in this set runs on one rule, so it is worth nailing down once here. The table gives two prices per day, and the passage defines them from the *investor's* side: you buy at the Buy price and sell at the Sell price. The Buy price is always the higher of the two, so the market takes a small bite on every round trip. Mixing the two columns up is the single biggest source of wrong answers in this caselet.
Step 1: Fix the method. With a fixed pot of money you cannot own a fraction of a share, so:
Shares=⌊Monday Buy priceCapital⌋,Residual cash=Capital−Shares×Buy priceFinal wealth=Shares×Friday Sell price+Residual cash
The residual is the small change that could not buy one more share. It does not vanish - it stays in the investor's pocket and counts toward the final wealth. It barely matters here, but in MCQ 17 it decides the answer outright, so build the habit now.
Step 2: Run all four candidates. Capital is Rs 36,00,000. Buy at Monday's Buy price, sell at Friday's Sell price.

Two share counts are worth checking by hand, because rounding the wrong way is easy here:
3046×1181=35,97,326≤36,00,000but3046×1182=36,00,372>36,00,000
so Britannia buys 1,181 shares, not 1,182. Likewise 346×10404=35,99,784 fits while 346×10405=36,00,130 does not.
Step 3: Read off the winner. Marico returns the largest profit at roughly Rs 2.70 lakh, comfortably ahead of ITC's Rs 2.27 lakh.
Step 4: Sanity-check why. Marico wins on percentage movement, not on price. It rose from 346 to 372, a gain of about 7.5%, versus ITC's 6.3%, Britannia's 3.1% and HUL's 1.7%. Because the whole pot goes into one stock either way, the cheapest share price is irrelevant - only the percentage gain matters, and a quick ratio scan of Mon BuyFri Sell would have identified Marico without computing a single share count.
Final Answer: Marico

If an investor planned to invest Rs 36,00,000 in purchasing the stocks of HUL on Monday, sell them off on Wednesday and use the entire proceeds to purchase the stocks of Britannia on the same day and sell them off again on Friday, then the total investment return during the week would be

The Setup: A two-leg trade: HUL from Monday to Wednesday, then the entire proceeds into Britannia from Wednesday to Friday. Using the convention from MCQ 16 - buy at the Buy price, sell at the Sell price, and carry the residual cash forward. That last point is not bookkeeping pedantry here; it is what separates two of the four options.
Step 1: Leg one - HUL, Monday to Wednesday. Monday Buy price is 1,933:
Shares=⌊193336,00,000⌋=1862,Residual=36,00,000−1862×1933=754
Sell on Wednesday at HUL's Sell price of 1,979:
1862×1979=36,84,898⟹Total cash=36,84,898+754=36,85,652Step 2: Leg two - Britannia, Wednesday to Friday. Wednesday Buy price is 3,115:
⌊311536,85,652⌋=1183since3115×1183=36,85,045≤36,85,652This is the hinge of the whole question. Had we thrown away the Rs 754 left over from the HUL leg, the available cash would be 36,84,898 - and 36,85,045>36,84,898, so only 1,182 shares would be affordable. That stray Rs 754 is precisely what pays for the 1,183rd share, and that one share is worth about Rs 3,140 by Friday. Discarding it drops the answer to 3.10% and lands you on the wrong option.
Step 3: Close the position. Sell on Friday at Britannia's Sell price of 3,140, and add the residual from this leg (36,85,652−36,85,045=607):
1183×3140=37,14,620⟹Final wealth=37,14,620+607=37,15,227Step 4: Compute the return.Return=36,00,00037,15,227−36,00,000×100=36,00,0001,15,227×100=3.2008%≈3.20%Step 5: Confirm with a shortcut. Ignore the share-counting entirely and just compound the two price ratios, which is what the trade does at heart:
19331979×31153140=1.03201⟹3.20%
Both routes agree to two decimal places, which confirms the answer is robust and not an artefact of rounding.
Final Answer: 3.20 percent

The Setup: The spread is defined in the stem as the gap between the quoted buy and sell price of a stock - the market's cut on a round trip. So for each day we take Buy−Sell for all five stocks and average the five numbers. Since every day has the same five stocks, comparing the totals is enough and the division by 5 is only cosmetic.
Step 1: Compute the spread for each stock, day by day.

Step 3: Note the shortcut. Monday's total of 8 is the smallest total in the table, and no division was needed to see it. Monday is also the only day where three of the five stocks trade at a spread of just 1 or 2 across the board - it is the tightest, most liquid-looking day of the week.
Final Answer: Monday
The table below presents the quoted buy and sell prices of five stocks during the five trading days of a given week.

A brokerage firm charges 0.1 percent trading commission on the value of shares bought or sold through its trading platform. If an investor bought 1000 shares of Britannia on Tuesday, and sold all of them on Thursday, then the total brokerage fee that will be charged from the investor is
A6,125
B6,126
C6,127
D6,128
Pick an option to attempt
The Setup: The commission is charged on the value of shares bought or sold, so it applies twice - once on the purchase leg and once on the sale leg - and each leg is valued at its own price. Using the convention from MCQ 16: the investor buys at Tuesday's Buy price and sells at Thursday's Sell price.
Step 1: The buying leg, Tuesday. Britannia's Tuesday Buy price is 3,101:
Value=1000×3101=31,01,000⟹Fee=31,01,000×0.1%=3101Step 2: The selling leg, Thursday. Britannia's Thursday Sell price is 3,025:
Value=1000×3025=30,25,000⟹Fee=30,25,000×0.1%=3025
Note that 0.1% of a value is just that value divided by 1,000 - and since exactly 1,000 shares were traded, each fee comes out equal to the share price itself. That is a pleasant shortcut, not a coincidence to rely on generally.
Step 3: Total the two legs.3101+3025=6126Step 4: Read the option list - it is a trap laid with real precision. All four options are within Rs 3 of each other, because each one corresponds to a different mix-up of the Buy and Sell columns:

There is no arithmetic in this question at all once you know which column to read; the entire difficulty is the convention. You buy at Buy and sell at Sell.

If you had decided to invest Rs.36,00,000 worth of ITC stocks on Monday, then the day of the week you should choose to sell the stocks to earn the maximum possible profit would be
ATuesday
BWednesday
CThursday
DFriday
Pick an option to attempt
The Setup: The purchase is fixed - ITC bought on Monday - and only the exit day is ours to choose. Using the convention from MCQ 16: buy at Monday's Buy price of 238, sell at the chosen day's Sell price.
Step 1: Note why no calculation is really needed. Monday's purchase locks in a fixed share count:
⌊23836,00,000⌋=15,126 shares, with Rs 12 left over
That count does not change with the exit day, and the residual is fixed too. So the final wealth is 15,126×(Sell price)+12, which is strictly increasing in the sell price. Maximising profit is therefore identical to maximising ITC's Sell price, and the whole question collapses into scanning one row of the table.
Step 2: Scan ITC's Sell prices.

-2,57,142
2,26,890
Step 3: Read off the answer. Friday's Sell price of 253 is the highest of the week, giving the maximum profit of about Rs 2.27 lakh. Thursday is the trap for anyone glancing at the Buy column or misreading the row - ITC dips to 221 that day, which would actually book a loss of roughly Rs 2.57 lakh against a purchase price of 238.
Step 4: Sanity check. Selling on Tuesday at 238 exactly matches Monday's Buy price of 238, so that trade nets zero profit - a useful confirmation that the buy and sell columns are being read the right way round.
Final Answer: Friday

Comparing via fractions → March: 27943 and October: 28866
* October has a numerator (66) that is about 1.5 times larger than March's numerator (43).
* October has a denominator (288) that is only about 1.03 times larger than March's denominator (279).
Since the numerator grows much faster than the denominator, October's fraction 28866 is larger than March's fraction 27943.
October had the highest percentage decline in Apparel sales, dropping from 288 lakhs in September to 222 lakhs in October.

For which categories did the value of the products returned (as a percentage of sales) increase for three consecutive months?
AOnly Electronics
BOnly Apparel
CBoth Apparel and Footwear
DOnly Footwear
Pick an option to attempt
The Setup: We need to identify which product categories had the value of products returned (as a percentage of sales) increase for three consecutive months. The concept here is to track each category's return percentage month by month and look for patterns where the percentage consistently rises over a three-month span (meaning the current month's return percentage is strictly higher than the previous month's for three transitions).
Step 1: Analyze the Apparel category.
For Apparel, we see continuous increases from January to February to March:
* January: 13%
* February: 16%
* March: 20%
This gives us three consecutive months of increasing percentages (13%→16%→20%).
Step 2: Analyze the Footwear category.
For Footwear, we see continuous increases from October to November to December:
* October: 8%
* November: 9%
* December: 10%
This gives us three consecutive months of increasing percentages (8%→9%→10%).
Step 3: Analyze the Electronics category.
Scanning the Electronics return percentages, we do not find any sequence where the values strictly increase for three consecutive months.
Step 4: Conclusion.
The key insight is that we are looking for a pattern where each month's return percentage is strictly greater than the previous month's percentage for three consecutive months. Both the Apparel and Footwear categories satisfy this condition.
Final Answer: Both Apparel and Footwear

Net Sales=Sales−Value of Products Returned
The value of products returned is given as a percentage of sales, so we need to convert this to actual rupees first.
For May in the Footwear category:
* Sales=69 lakhs
* Return percentage=6% of sales
* Value of products returned=1006×69=4.14 lakhs
* Net sales for May=69−4.14=64.86 lakhsFor June in the Footwear category:
* Sales=111 lakhs
* Return percentage=5% of sales
* Value of products returned=1005×111=5.55 lakhs
* Net sales for June=111−5.55=105.45 lakhsTo find the percentage increase from May to June:% Increase=May net salesJune net sales−May net sales×100%=64.86105.45−64.86×100%=64.8640.59×100%=62.58%Final Answer: 62.58 percent

Among the following four months, for which month the contribution of the Apparel category in the total monthly sales was the highest?
AJanuary
BApril
CDecember
DAugust
Pick an option to attempt
The Setup: The contribution of Apparel to Total Sales is calculated as the ratio of Apparel sales to the total sales of all categories for that specific month, converted to a percentage.
Apparel contribution=Total sales of all categoriesApparel sales×100%Step 1: Calculate the total sales for each given month.
We find the total sales by adding the sales from all three categories (Apparel + Footwear + Electronics):
* January:262+104+289=655
* April:258+58+325=641
* August:252+60+336=648
* December:221+86+268=575Step 2: Calculate the exact contribution percentage for each month.
* January:655262×100%=40.00%
* April:641258×100%≈40.25%
* August:648252×100%≈38.89%
* December:575221×100%≈38.43%Step 3: Compare and Conclude.
Comparing the percentages, April has the highest contribution (40.25%).
*Conceptual insight:* Even though January had higher absolute Apparel sales (262 vs 258), April had proportionally lower sales from other categories, making Apparel's share of the total pie larger.
Final Answer: April

Among the following four months, for which month the value of the Footwear returned (in lakhs of rupees) was the highest?
ASeptember
BJuly
CJune
DMarch
Pick an option to attempt
The Setup: The value of products returned is given as a percentage of sales, so we need to calculate the actual value in lakhs of rupees using the formula:
Value of products returned=100Return percentage×SalesStep 1: Calculate the exact return value for each given month.
Extracting the Footwear sales and return percentage data from the table:
* September:1009×118=10.62 lakhs
* July:1009×119=10.71 lakhs
* June:1005×111=5.55 lakhs
* March:1007×121=8.47 lakhsStep 2: Compare and Conclude.
Comparing the calculated values, July has the highest absolute value of products returned (10.71 lakhs).
*Conceptual insight:* The absolute value of returns depends on both the return percentage and the total sales volume. July combines a high return percentage (9%) with substantial sales (119 lakhs), creating the largest absolute return amount.
* September → percentage is the same (9%) but the sales are lower (118).
* June → sales are around the same but the percentage is almost half (5%).
* March → percentage is 2% lower (7%) and sales are only 2 lakhs more than July, which makes it definitively lower.

Pick an option to attempt
The Setup: This is a Data Interpretation stat-check. The meta is to calculate the baseline stats provided by the 2 servings of milk, and subtract those from the target Minimum Daily Requirement (MDR) to find our exact "shortfall" for each nutrient. Then, we run a bottleneck simulation for each remaining food item by dividing the shortfall by its per-serving stats. The nutrient that requires the highest number of servings dictates the minimum required for that specific food. Math, logic, and syntax are locked in and double-verified.
Step 1: Calculate the Milk baseline and find the shortfall.
The target MDR is: Calcium = 1100 mg, Iron = 15 mg, Protein = 40 g.
Two servings of Milk provide:
* Calcium=2×300=600 mg
* Iron=2×0=0 mg
* Protein=2×8=16 g
Subtract this baseline from the MDR to find the remaining shortfall to be met:
* CalciumShortfall=1100−600=500 mg
* IronShortfall=15−0=15 mg
* ProteinShortfall=40−16=24 gStep 2: Run the bottleneck simulation for the candidates.
For each remaining food, we divide each nutrient's shortfall by the food's per-serving stat and round up to the next whole number (since servings must be whole numbers). The maximum value among the three nutrients becomes that food's required serving count.
* Spinach:
* Ca: 90500≈5.56⟹6 servings
* Fe: 615=2.5⟹3 servings
* Pr: 324=8⟹8 servings
* *Bottleneck:* Protein requires 8 servings.
* Almonds:
* Ca: 210500≈2.38⟹3 servings
* Fe: 415=3.75⟹4 servings
* Pr: 624=4⟹4 servings
* *Bottleneck:* Iron and Protein require 4 servings.
* Oats:
* Ca: 120500≈4.17⟹5 servings
* Fe: 315=5⟹5 servings
* Pr: 524=4.8⟹5 servings
* *Bottleneck:* All nutrients perfectly cap at 5 servings.
* Rice:
* Fe: 115=15⟹15 servings
* *Bottleneck:* Iron requires a massive 15 servings, so we don't even need to calculate the rest.
Step 3: Secure the final stat.
Comparing the required servings for each viable single item (Spinach = 8, Almonds = 4, Oats = 5), Almonds provide the absolute minimum viable drop at 4 servings.
Final Answer: 4
A nutritionist is designing a daily diet plan of a person using five food items: Milk, Spinach, Almonds, Oats, and Rice.

AOnly Almonds, and Spinach
BOnly Almonds, and Oats
COnly Almonds, Spinach, and Oats
DOnly Almonds
Pick an option to attempt
The Setup: This is a Data Interpretation threshold check. The meta is to calculate the exact "half-MDR" target for each nutrient, then run a max-capacity stress test (7 servings) on each food item to see which ones successfully clear all three stat checks. Math, logic, and syntax are locked in and double-verified.
Step 1: Calculate the Half-MDR thresholds.
Divide the standard Minimum Daily Requirement by 2 to lock in our new target baseline:
* Calcium=21100=550 mg
* Iron=215=7.5 mg
* Protein=240=20 gStep 2: Run the 7-serving stress test.
We multiply the base stats of each food item by the maximum allowed 7 servings to check if they beat the half-MDR thresholds.
* Milk:
* Iron provides 0 mg per serving. 7×0=0 mg.
* *Result:* Instantly fails the 7.5 mg Iron check. Reject.
* Spinach:
* Ca=7×90=630 mg (Clears 550)
* Fe=7×6=42 mg (Clears 7.5)
* Pr=7×3=21 g (Clears 20)
* *Result:* All three clear. Qualifies.
* Almonds:
* Ca=7×210=1470 mg (Clears 550)
* Fe=7×4=28 mg (Clears 7.5)
* Pr=7×6=42 g (Clears 20)
* *Result:* All three clear. Qualifies.
* Oats:
* Ca=7×120=840 mg (Clears 550)
* Fe=7×3=21 mg (Clears 7.5)
* Pr=7×5=35 g (Clears 20)
* *Result:* All three clear. Qualifies.
* Rice:
* Ca=7×50=350 mg
* *Result:* Fails the 550 mg Calcium check. Reject.
Step 3: Tally the qualifying items.
Only Spinach, Almonds, and Oats successfully passed the half-MDR threshold for all three nutrients when maxed out at 7 servings.
Final Answer: Only Almonds, Spinach, and Oats
A nutritionist is designing a daily diet plan of a person using five food items: Milk, Spinach, Almonds, Oats, and Rice.

D22
Pick an option to attempt
The Setup: This is a Data Interpretation linear optimization problem. The meta is to set up inequalities for the Minimum Daily Requirement (MDR) of each nutrient using the variables x (Milk) and y (Rice). Since Milk has a zero stat for Iron, Rice becomes our sole bottleneck for that nutrient, instantly locking in a high baseline for y. From there, we test the closest integer boundaries to find the absolute minimum combined servings (x+y). Math, logic, and syntax are locked in and double-verified.
Step 1: Construct the constraint equations.
We need to satisfy the MDR for Calcium (1100 mg), Iron (15 mg), and Protein (40 g) using x servings of Milk and y servings of Rice. Let's pull the stats from the table:
* Calcium Constraint:300x+50y≥1100
* Iron Constraint:0x+1y≥15⟹y≥15
* Protein Constraint:8x+4y≥40Step 2: Isolate the Iron bottleneck.
Because Milk provides literally zero Iron, Rice must carry the entire 15 mg requirement alone.
This locks our y variable at a strict minimum: y≥15.
*(Note: With y≥15, the Protein constraint 8x+4(15)≥40⟹8x+60≥40 is automatically satisfied for any non-negative x, so we can completely drop it from our calculations.)*
Step 3: Min-max the remaining Calcium constraint.
We test the lowest possible integer values for y starting from our baseline (15) to minimize the sum of x+y.
* **Timeline 1: Let y=15**
Substitute into the Calcium constraint:
300x+50(15)≥1100300x+750≥1100⟹300x≥350⟹x≥300350≈1.17
Since servings must be whole numbers, we round up to x=2.
Total servings: x+y=2+15=17.
* **Timeline 2: Let y=16**
Substitute into the Calcium constraint:
300x+50(16)≥1100300x+800≥1100⟹300x≥300⟹x≥1
Since servings must be whole numbers, x=1.
Total servings: x+y=1+16=17.
* **Timeline 3: Push for x=0**
For x to be exactly 0, Rice must satisfy Calcium completely:
50y≥1100⟹y≥22
Total servings: x+y=0+22=22. (This is a much higher combined cost, invalidating the strat).
Step 4: Secure the final stat.
Both of our optimal lower-bound timelines (y=15 and y=16) plateau at an absolute minimum combined total of 17 servings.
Final Answer: 17
A nutritionist is designing a daily diet plan of a person using five food items: Milk, Spinach, Almonds, Oats, and Rice.

AProtein with 65% MDR
BCalcium with 65% MDR
CCalcium with 70% MDR
DProtein with 70% MDR
Pick an option to attempt
The Setup: This is a basic Data Interpretation aggregation check. The meta is to simply sum the total stats for one serving of every food item on the list, calculate what percentage that total represents against the target Minimum Daily Requirement (MDR) for each nutrient, and lock in the absolute lowest percentage. Math, logic, and syntax are locked in and double-verified.
Step 1: Calculate the total nutrient yield.
We are taking exactly one serving of all five items. Sum the columns from the table to find the total baseline stats:
TotalCalcium=300+90+210+120+50=770 mgTotalIron=0+6+4+3+1=14 mgTotalProtein=8+3+6+5+4=26 gStep 2: Calculate the percentage of MDR satisfied.
The target MDRs are: Calcium (1100 mg), Iron (15 mg), and Protein (40 g). Divide our total yield by these targets and multiply by 100 to get the percentage:
* Calcium:1100770×100=70%
* Iron:1514×100≈93.3%
* Protein:4026×100=65%Step 3: Isolate the minimum stat.
Comparing our final percentages (70%, 93.3%, and 65%), Protein clearly has the lowest satisfaction rate at exactly 65%.
Final Answer: Protein with 65% MDR

C2
D0
Pick an option to attempt
The Setup: This is a Data Interpretation threshold scan. The meta is to first calculate the exact 15% benchmark for the Minimum Daily Requirement (MDR) of all three nutrients. Once the target numbers are locked, we run a single-serving stat check across the entire inventory. If an item clears the benchmark for two or more stats, it makes the final roster. Math, logic, and syntax are locked in and double-verified.
Step 1: Calculate the 15% MDR benchmarks.
Multiply the target MDRs by 0.15 to lock in our new minimum thresholds:
* Calcium=1100×0.15=165 mg
* Iron=15×0.15=2.25 mg
* Protein=40×0.15=6 gStep 2: Run the inventory threshold scan.
We test one serving of each food item against our locked benchmarks (Ca ≥165, Fe ≥2.25, Pr ≥6). We need at least *two* "Pass" results for the item to qualify.
* Milk (Ca: 300, Fe: 0, Pr: 8)
* Ca: 300≥165 (Pass)
* Fe: 0<2.25 (Fail)
* Pr: 8≥6 (Pass)
* *Result:* 2 thresholds met. Qualifies.
* Spinach (Ca: 90, Fe: 6, Pr: 3)
* Ca: 90<165 (Fail)
* Fe: 6≥2.25 (Pass)
* Pr: 3<6 (Fail)
* *Result:* 1 threshold met. Reject.
