Question: Frank picked 36 apples. Susan picked 3 times as many apples as Frank. If Susan gave out half of her apples, and Frank sold a third of his, how many in total do they have left?
Answer: Step-by-step reasoning process: Susan picked 3 times as much as 36 which is 3 * 36 = 108 apples. She gave out half which is 108 * (1 / 2) = 54 apples. She now has 108 - 54 = 54 apples. Frank sold a third of 36 which is 36 * (1 / 3) = 12 apples. Frank now has 36 - 12 = 24 apples. Altogether they now have 54 + 24 = 78 apples.
So the answer is 78.

Question: Harry is joining a marathon that's why he practices and varies his workouts from day to day. He ran 10 meters per hour on Monday. From Tuesday to Thursday he ran 50% faster than on Monday. Then on Friday, he ran 60% faster than he ran on Thursday. How fast did Harry run on Friday?
Answer: Step-by-step reasoning process: Harry ran 10 x 50 / 100 = 5 meters per hour faster on Tuesday to Wednesday. So he ran 10 + 5 = 15 meters per hour from Tuesday to Thursday. Then on Friday, he ran 15 x 60 / 100 = 9 meters per hour more. Therefore, he ran 15 + 9 = 24 meters per hour on Friday.
So the answer is 24.
