Question

If 3 cats eat 3 mice in 3 minutes, then in how many days will 1 cat eat 1 rat.​

Answer 1

If 3 cats catch 3 rats in 3 minutes, then 1 cat can catch 1 rat in the same 3 minutes, or put another way, a single cat can catch 1/3 of a rat per minute. So 1 cat can catch 33 1/3 rats in 100 minutes, so 3 cats can catch 100 rats in 100 minutes
