Answer: 27
Step-by-step 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
[tex]\Rightarrow x+3+3=2x\\\Rightarrow x=6[/tex]
In three day time, it is
[tex]\Rightarrow x+x+3+2x\\\Rightarrow 4x+3\\\Rightarrow 4\times 6+3=27[/tex]
