21. One apple pie has 10 slices, and each apple pie feeds five people. Henry is having a party with 200 people. How many slices of pie does he need?

• A. 200
• B. 50
• C. 400
• D. 100

Explanation: Feeding 200 people at five people per pie needs 40 pies, and at 10 slices each that is 400 slices. Equivalently, each person eats two slices, so 200 people need 400. The distractor 200 comes from assuming one slice per person, which contradicts the figures given.

22. Asad bought 50 packets of biscuits for the price of Rs. 500, whereas Anum bought 25 packets of chips for the price of Rs. 1000. While comparing the prices of packets of biscuits and packet of chips, which of the following statements is correct?

• A. Price of 4 packets of biscuits is equal to the price of 1 packet of chips
• B. Price of 1 packet of biscuits is equal to the price of 4 packets of chips
• C. Price of 2 packets of biscuits is equal to the price of 1 packet of chips
• D. Price of 1 packet of biscuits is equal to the price of 2 packets of chips

Explanation: A packet of biscuits costs 500 divided by 50, that is Rs. 10, and a packet of chips costs 1000 divided by 25, that is Rs. 40, so one packet of chips equals four packets of biscuits. Reducing both to a unit price before comparing is what makes the ratio obvious. The reversed options describe biscuits as the more expensive item, which the arithmetic contradicts.
