Question: There were 100 jelly beans in a bag to be given away on Halloween. Out of the 40 children taking part in the Halloween celebration, 80% were allowed to draw jelly beans from the bag. Each child drew two jelly beans out of the bag. How many jelly beans remained in the bag after the children took their share?
Answer with step-by-step thinking: Out of the 40 children taking part in the Halloween celebration, 80% were allowed to draw jelly beans from the bag, a total of 80 / 100 * 40 = 32 children. If each of the 32 children drew two jelly beans out of the bag, they drew a total of 32 * 2 = 64 jelly beans from the bag. The total number of jelly beans that remained is 100 - 64 = 36.
So the answer is 36.


Question: Tom's rabbit can run at 25 miles per hour. His cat can run 20 miles per hour. The cat gets a 15-minute head start. In hours, how long will it take for the rabbit to catch up?
Answer with step-by-step thinking: The cat got a 15 / 60 = .25 hour head start. That means it ran 20 * .25 = 5 miles. The rabbit goes 25 - 20 = 5 mph faster than the cat. So it takes 5 / 5 = 1 hour for the rabbit to catch up.
So the answer is 1.


Question: Caleb, Andy and Billy went on a picnic with their father. Billy took 6 candies with him, Caleb took 11 and Andy left with 9. On the way, their father bought a packet of 36 candies. He gave 8 candies to Billy, 11 to Caleb and the rest to Andy. How many more candies does Andy now have than Caleb?
Answer with step-by-step thinking:
Billy took some candies and got more from his father for a total of 6 + 8 = 14 candies. Caleb has a total of 11 + 11 = 22 candies. Their father gave out 8 + 11 = 19 candies from a pack of 36. He gave the rest which is 36 - 19 = 17 candies to Andy. Andy has a total of 9 + 17 = 26 candies. Andy has 26 - 22 = 4 more candies than Caleb.
So the answer is 4.
