[Question]: Alice had 10 dozens of watermelons. She sold 40% of it yesterday and 1/4 of the remaining today, How many watermelons are left to be sold tomorrow?
[Answer]: Ten dozens of watermelons are equal to 10 x 12 = 120 watermelons. Yesterday, Alice sold 120 x 40 / 100 = 48 watermelons. So, there are only 120 - 48 = 72 watermelons left for today. Today, Alice sold 72 x 1 / 4 = 18 watermelons. Hence, 72 - 18 = 54 watermelons are left to be sold tomorrow.
So the answer is 54.

[Question]: Making an equal number of drums of paint each day, a paint mixer takes three days to make 18 drums of paint. How many days will it take for him to make 360 drums of paint?
[Answer]:
If a paint mixer takes three days to make 18 drums of paint in a day, he makes 18 / 3 = 6 drums of paint. The number of days it will take for him to make 360 drums of paint, making 6 drums a day, is 360 / 6 = 60 days.
So the answer is 60.
