Question: Janet goes to the gym for 5 hours a week. She goes Monday, Tuesday, Wednesday, and Friday. She spends an hour and a half each day on Monday and Wednesday. If she spends the same amount of time at the gym on Tuesday and Friday how many hours is she at the gym on Friday?


Jeff donated 30 / 100 * 300 = 90 pencils. He remained with 300 - 90 = 210 pencils. Vicki had twice as many pencils as Jeff, meaning he had 2 * 300 = 600 pencils. When Vicki donated 3 / 4 of his pencils, he gave away 3 / 4 * 600 = 450 pencils. Vicki remained with 600 - 450 = 150 pencils. Together, Jeff and Vicki remained with 150 + 210 = 360 pencils.
The answer: 360
Reverse engineering the question: Jeff had 300 pencils and donated 30% of them. Vicki had twice as many pencils as Jeff and donated 3/4 of his pencils. How many pencils are there remaining altogether?


Reasoning and answer: If she bought a 500 pages book and wrote on 150 pages, the number of empty pages remaining is 500 - 150 = 350 pages. She then wrote on 30% of the remaining empty pages on the second week, a total of 30 / 100 * 350 = 105 pages. The number of remaining empty pages is 350 - 105 = 245 pages. When she spilled coffee on the remaining empty pages, the number of damaged pages was 20 / 100 * 245 = 49. The number of empty pages remaining that she could write on is 245 - 49 = 196 pages.
The answer: 196

D1 = 322. D3 = 2 * 322 = 644. D2 = 644 - 19 = 625. 322 + 625 + 644 = 1591. There are 1591 voters in Districts 1 - 3.
The answer: 1591
Reverse engineering the question: There are 322 voters in District 1. District 2 has 19 less voters than District 3. District 3 has twice as many voters as District 1. How many total voters are in Districts 1 - 3?


Reasoning and answer: In one day the shop is losing 5 thousand dollars, so during three days, the losses are 5 * 3 = $15,000. Christmas holidays are once a year, so in 6 years the shop "Surprise" could have earned another $15,000 * 6 = $90,000.
The answer: 90000

Question: During the Christmas holidays, all shops are closed for 3 days. During each day during this time, a shop called "Surprise" could have earned 5 thousand dollars. How much potential revenue did the "Surprise" shop lose during 6 years of activity?


Reasoning and answer: If he sold a painting at a 10% loss, then he made a 10 / 100 * $40 = $4 loss on each painting. since he bought 10 paintings, the total loss he made from selling the paintings is 10 * $4 = $40. He also made a loss of 15 / 100 * 20 = $3 loss from selling each wooden toy. Since he bought 8 wooden toys, the total loss he made was 3 * 8 = $24. In total, Mr. Callen made a loss of $40 + $24 = $64 from the sales of the items.
The answer: 64
