We have a question: There are six oranges in a fruit basket. There are two fewer apples than oranges. There are 3 times as many bananas as apples, and there are half as many peaches as bananas. How many pieces of fruit are in the fruit basket?
And an answer: 28
So how you got the answer?
There are 6 - 2 = 4 apples. There are 3 * 4 = 12 bananas. There is 1 / 2 x 12 bananas = 6 peaches. There is 6 oranges + 4 apples + 12 bananas + 6 peaches = 28 pieces of fruit.

We have a question: Rita bought 5 short dresses, 3 pairs of pants and 4 jackets from a store that sells second-hand clothes. The dresses cost $20 each, the pants cost $12, the jackets cost $30 each, and she spent an additional $5 on transportation. If she had $400 initially, how much does she have now?
And an answer: 139
So how you got the answer?
She bought 5 dresses at $20 each for a total of 5 * $20 = $100. She bought 3 pairs of pants at $12 each for a total of 3 * $12 = $36. She bought 4 jackets at $30 each for a total of 4 * $30 = $120. She spent an additional $5 on transportation for a sum total of $5 + $100 + $36 + $120 = $261. She initially had $400 so she now has $400 - $261 = $139.

We have a question: Christian is twice as old as Brian. In eight more years, Brian will be 40 years old. How old will Christian be in eight years?
And an answer: 72
So how you got the answer?
If in eight years Brian will be 40 years old, he is currently 40 - 8 = 32 years old. Since Christian is twice as old as Brian, he is 2 * 32 = 64 years old. In 8 years, Christian will be 64 + 8 = 72 years old.
