Brain Teasers: Kagome Fruit & Vegetable Puzzle Solutions

Clean the Room Together Puzzle Solution:
Parsley and Peach can clean the room in 3 hours alone. They clean 1/3 room per hour. Beet and Lemon could do it in 2 hours alone. They clean 1/2 room per hour.

If the teams worked together, they can clean 1/2 + 1/3 room per hour.

1/2 + 1/3 equals 3/6 + 2/6 or 5/6 of the room cleaned in the first hour. That means that 1/6 of the room is cleaned in every 12 minutes (60 minutes in one hour divided by 5 equals 12 minutes). So to finish the room, the team would need another 12 minutes.

The room would be cleaned in one hour and 12 minutes.
