Reasoning and answer: The tree drops 340 / 10 = 34 leaves for each of the four days. Thus, it drops 34 * 4 = 136 leaves over the first four days. Therefore, it drops 340 - 136 = 204 leaves on the fifth day.
The answer: 204

Question: In the fall, a tree drops a tenth of its initial quantity of leaves each day over the course of four days, then abruptly drops the rest on the fifth day. If it had 340 leaves before they started to fall, how many leaves does it drop on the fifth day?
He shucks 10 oysters in 5 minutes we need to know how many 5 minute units are in 60 minutes so 60 / 5 = 12 units. He can shuck 10 oysters in 5 minutes and there are 12 5 minute units in an hour so he can shuck 10 * 12 = 120 oysters in 1 hour. If he can shuck 120 oysters in 1 hour, so for 2 hours in can shuck 2 * 120 = 240 oysters.
The answer: 240
Reverse engineering the question: Bob can shuck 10 oysters in 5 minutes. How many oysters can he shuck in 2 hours?
Reasoning and answer: If Felix drives twice as fast, he will be covering 2 * 66 = 132 miles per hour. In four hours, driving at 132 miles per hour, since distance = speed * time, Felix will cover 132 * 4 = 528 miles.
The answer: 528
What was the question?
Question: The average speed for an hour drive is 66 miles per hour. If Felix wanted to drive twice as fast for 4 hours, how many miles will he cover?
He bought 10 / 2 = 5 pants. The shirts cost a total of 10 * 6 = $60. The pants cost 8 * 5 = $40. So the total cost was 60 + 40 = $100.
The answer: 100
Reverse engineering the question: James buys 10 shirts and half as many pants. The shirts cost $6 each and the pants cost $8 each. How much did everything cost?
Reasoning and answer: Jose collected 80 - 14 = 66 rocks. Albert collected 66 + 20 = 86 rocks. Thus, Albert collected 86 - 80 = 6 more rocks than Joshua.
The answer: 6
What was the question?
Question: Joshua, Jose, and Albert are collecting rocks. Joshua collected 80 rocks while Jose collected 14 fewer rocks. Albert has collected 20 more rocks than Jose. How many more rocks did Albert collect than Joshua?
Reasoning and answer: First, the shop is open 12 hours * 60 minutes = 720 minutes per day. So, 720 / 30 = 24 women's T - shirts sold per day. The shop earns 24 * $18 = $432 selling women's T - shirts per day. Similarly, 720 / 40 = 18 men's T - shirts are sold per day. The shop earns 18 * $15 = $270 selling men's T - shirts per day. The shop earns $432 + $270 = $702 per day selling T - shirts. The shop earns $702 * 7 = $4914 per week.
The answer: 4914
