We have a question: Josh gets together with 7 friends. Everyone including him puts 5 dollars into a pot. First place gets 80% of the money. Second and third place split the rest. How much money does third place get?
And an answer: 4
So how you got the answer?
7 + 1 = 8 people threw money into the pot. So the amount of money in the pot is 8 * 5 = $40. First place gets 40 * .8 = $32. So there is 40 - 32 = $8 left in the pot after first place gets his cut. So third place gets 8 / 2 = $4.

We have a question: Susan, Arthur, Tom and, Bob are siblings. Arthur is 2 years older than Susan, and Tom is 3 years younger than Bob. If Bob is 11 years old, and Susan is 15 years old, how old are all four family members in total?
And an answer: 51
So how you got the answer?
Arthur is 2 years older than Susan, so he is 15 + 2 = 17 years old. Bob is 11 years old, so Tom is 11 - 3 = 8 years old. So in total these four family members have 11 + 15 + 17 + 8 = 51 years.

We have a question: The age of a lioness in a park is twice the age of a hyena in the same park. The lioness is 12 years old. If the babies of the two animals are half the age of their mothers, calculate the sum of the age of the babies in five years.
And an answer: 19
So how you got the answer?
If the lioness is 12 years old, the hyena, half her age, is 12 / 2 = 6 years old. The baby of the lioness is 12 / 2 = 6 years old, half the mother's age. Five years from now, the age of the lioness's cub will be 6 + 5 = 11. The baby of the hyena is 6 / 2 = 3 years old, which is half the mother's age. The hyena's baby will be 3 + 5 = 8 years old in five years. Together, the total age of the babies will be 8 + 11 = 19 years in five years.
