One clerk can process 25 x 8 = 200 forms in a day. To process the forms for that day 2400 / 200 = 12 clerks must be hired.
The answer: 12
Reverse engineering the question: A clerk can process 25 forms per hour. If 2400 forms must be processed in an 8-hour day, how many clerks must you hire for that day?

There were 9 - 4 = 5 other pills. Each of the other pills cost 1.50 + 5.50 = 7 dollars each. The 5 pills cost a total of 7 * 5 = 35 dollars. The first 4 pills cost 1.50 * 4 = 6 dollars in total. Henry spent a total of 35 + 6 = 41 dollars.
The answer: 41
Reverse engineering the question: Henry took 9 pills a day for 14 days. Of these 9 pills, 4 pills cost $1.50 each, and the other pills each cost $5.50 more. How much did he spend in total on the pills?

He has 60 - 20 = 40 kilograms of mangoes left after selling them to the market. Colby sold 1 / 2 x 40 = 20 kilograms of mangoes to the community. Therefore, Colby still has 20x8 = 160 pieces of mangoes.
The answer: 160
Reverse engineering the question: Colby harvested his mango trees, the total mangoes he harvested is 60 kilograms. He sold 20 kilograms to the market and sold the remaining half to his community. If each kilogram contains 8 mangoes, how many mangoes does he still have?

There are 30 + 15 + 40 = 85 minutes accounted for. She spent 2 * 60 = 120 minutes. She spent 120 - 85 = 35 minutes cleaning her room.
The answer: 35
Reverse engineering the question:
Miriam spent 30 minutes doing laundry, 15 minutes cleaning the bathroom, a certain amount of time cleaning her room, and 40 minutes doing homework. If she spent a total of two hours on these tasks, how long, in minutes, did she spend cleaning her room?
