Consider the Q and A. Q: Cindy was 5 years old. Her sister Jan was 2 years older than Cindy. Their oldest sister Marcia was twice as old as Jan. Greg was two years older than Marcia. How old was Greg?
A: 16
What is the step-by-step reasoning process?
Step-by-step reasoning process: Jan was 2 years older than Cindy who was 5 so 2 + 5 = 7 years old. Marica was twice as old as Jan so 2 * 7 = 14 years old. Greg was 2 years older than Marcia who was 14 so 2 + 14 = 16 years old.

What is the step-by-step reasoning process?

Consider the Q and A. Q: Mike bought a DVD of his favorite movie. He paid $5 for it at the store. A friend of Mike's, Steve, saw this and also decided to buy a DVD of the movie, but it was already sold out. He needed to order it online, which cost him twice as much. And in addition, he needed to pay the shipping costs which were 80% of the price of the film he ordered. How much did Steve pay to get the DVD in total?
A: 18
What is the step-by-step reasoning process?
Step-by-step reasoning process: The cost of the movie online was twice what Mike paid, so 2 * 5 = $10. The shopping costs were standing at 80 / 100 * 10 = $8. So in total Steve paid 10 + 8 = $18.

Consider the Q and A. Q: How many apples did two men and three women buy at a certain store if the two men each bought 30 apples, 20 less than the number of apples bought by each woman?
A: 210
What is the step-by-step reasoning process?
Step-by-step reasoning process:
If the two men each bought 30 apples, together they bought 2 * 30 = 60 apples. Since the two men each bought 30 apples, 20 less than the total number of apples bought by each woman, each woman bought 20 + 30 = 50 apples. The total number of apples bought by the women is 3 * 50 = 150. Altogether, the two men and three women bought 60 + 150 = 210 apples.
