Question

During 3 days joy the cat was catching mice .Each day joy caught 3 mice more than the previous day .On the third day joy caught twice as many mice as on the first day . In total

how many mice did joy catch during the three days

Answer 1

Answer: 27

Explanation:

Given

During 3 days the cat was catching mice

Suppose the first-day joy caught x mice

So, on the second day, it is x+3

on the third day, joy catches twice as many mice as on the first day i.e. 2x

or we can also write, no of mice caught on the second day plus 3 is equal to no of mouse caught on the third day

`\Rightarrow x+3+3=2x\\\Rightarrow x=6`

In three day time, it is

`\Rightarrow x+x+3+2x\\\Rightarrow 4x+3\\\Rightarrow 4* 6+3=27`
