If 5 cats can catch 5 mice in 5 minutes, how many cats are needed to catch 100 mice in 100 min?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 5.
5 cats catch 5 mice in 5 minutes → each cat catches 1 mouse in 5 minutes
In 100 minutes, 1 cat catches: 100 ÷ 5 = 20 mice
To catch 100 mice: 100 ÷ 20 = 5 cats
