Katelyn made 49 + 47 = 96 sandwiches. Chloe made 96 / 4 = 24 sandwiches. Billy, Katelyn, and Chloe made 49 + 96 + 24 = 169 sandwiches in all.
The answer: 169
Reverse engineering the question: Billy made 49 sandwiches; Katelyn made 47 more than that. Chloe made a quarter of the amount that Katelyn made. How many sandwiches did they make in all?


Reasoning and answer: A bottle costs 1.50 € / 3 = 0.50 €. So, four bottles cost 0.50 € * 4 = 2 €.

The customers that bought one watermelon bought 1 * 17 = 17 melons. The customers that bought three melons bought 3 * 3 = 9 melons. The stand sold 46 - 17 - 9 = 20 melons to customers who bought 2 melons. Thus, 20 / 2 = 10 customers bought two watermelons.
The answer: 10
Reverse engineering the question: A watermelon stand sold 46 watermelons. Seventeen customers bought one melon, three customers bought three melons, and the rest bought two melons. How many customers bought two watermelons?

First find the number of matches the dog eats: 10 matches * 2 = 20 matches. Then subtract all the lost matches from the starting number to find the final number: 70 matches - 10 matches - 20 matches = 40 matches.
The answer: 40
Reverse engineering the question: Nate starts his camping trip with 70 matches. He drops 10 in a creek and his dog eats twice as many. How many matches does he have left?


Orlan gave Allan 20 x 1 / 4 = 5 meters of rope. So he had 20 - 5 = 15 meters left. Then he gave 15 x 2 / 3 = 10 meters of the rope to Jack. Therefore, Orlan is left with 15 - 10 = 5 meters of rope.
The answer: 5
Reverse engineering the question:
