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
A2.80 percent
B3.00 percent
C3.20 percent
D3.40 percent
Pick an option to attempt
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.

Worked out in full for Monday, the winning day:
5(462−460)+(346−345)+(1933−1931)+(238−237)+(3046−3044)=52+1+2+1+2=58=1.6Step 2: Compare. Monday's average of 1.6 is the lowest of the four days offered; Tuesday at 1.8 is the nearest rival.
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. The quoted sell price is the price at which an investor can sell a stock in the market. The quoted buy price is the price at which an investor can buy a stock from the market.

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:
Tuesday price used

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.
Final Answer: 6,126

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.

2,26,890
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
