Come up with a question and reasoning that would justify [60] as the answer.
The question is: On Mary's birthday, her brother surprised her with $100. She spent a quarter of it on a new video game and then used a fifth of what was left on swimming goggles. How much money did she have left?
Reasoning: Mary spent 100 / 4 = 25 dollars on a new video game. So, after the video game purchase, Mary was left with 100 - 25 = 75 dollars. Mary then bought swimming goggles for 75 / 5 = 15 dollars. Mary had 75 - 15 = 60 dollars left.
