On Monday, Joanna reads 3 * 16 = 48 pages. On Tuesday, Joanna reads 6.5 * 16 = 104 pages. So far, she has read 48 + 104 = 152 pages. Thus, she has 248 - 152 = 96 pages left. She will need to read for 96 / 16 = 6 hours to finish the book.
The answer: 6
Reverse engineering the question: There are 248 pages in a book. Joanna can read 16 pages per hour. On Monday, she reads for 3 hours. On Tuesday, she reads for 6.5 hours. How many more hours does she need to read to finish the book?
Reasoning and answer: If 3 / 5 of the people in the race are riding bicycles, their number is 3 / 5 * 40 people = 24 people. Since a bicycle has 2 wheels, and 24 people were riding on a bicycle each, the total number of bicycle wheels in the race is 2 wheels / bike * 24 bikes = 48 wheels. The number of racers on tricycles is 40 people - 24 people = 16 people. Since a tricycle has 3 wheels, and 16 people were riding on a tricycle each, the total number of tricycle wheels in the race is 3 wheels / trike * 16 trikes = 48 wheels. The combined total for bicycle and tricycle wheels in the race is 48 wheels + 48 wheels = 96 wheels.
The answer: 96

Question: A competition has racers competing on bicycles and tricycles to win a grand prize of $4000. If there are 40 people in the race, and 3/5 of them are riding on bicycles, how many wheels do the bicycles and tricycles in the race have combined?
Four times the number of pies that Mcgee's sold is 16 * 4 = 64 pies. Smith's Bakery sold 64 + 6 = 70 pies.
The answer: 70
Reverse engineering the question: Smith's Bakery sold 6 more than four times the number of pies that Mcgee's Bakery sold. If Mcgee's Bakery sold 16 pies, how many pies did Smith's Bakery sell?

Question: The coffee shop sold 8 more than four times the number of lattes as it did teas. If 6 teas were sold how many lattes did the coffee shop sell?
The payout for blackjack is 3:2 or 3 / 2 = 1.5 times my bet. If my original bet was X then I won 1.5 * X my bet. Given that I was paid $60 we know $60 = 1.5X. X = $60 / 1.5. X = $40 was my original bet.
The answer: 40
Reverse engineering the question: A casino table pays 3:2 if you get a blackjack with your first 2 cards. If you scored a blackjack and were paid $60, what was your original bet?
Half a pizza is the same as 3 / 6 of a pizza. 1 / 3 of a pizza is the same as 2 / 6 of a pizza. 3 / 6 of a pizza plus 2 / 6 of a pizza plus 1 / 6 of a pizza equals 6 / 6 of a pizza. Therefore, she needs to buy one pizza because 6 / 6 equals 1.
The answer: 1
