Answer 1

Nira's present age= 30

Explanation:

`her \: age \: before \: 10years \: = x - 10 \\ her \: age \: after \: 10years \: = x + 10 \\ therefore.(x - 10) + (x + 10) = 60 \\ x - 10 + x + 10 = 60 \\ 2x = 60 \\ x = 60 / 2 \\ x = 30 \\ hope \: it \: helps....`

Answer 2

I think Nira would be 30 years old

Explanation:

So 10 years before and after her present age added together equals 60. So if she was 30, it would be 20+40 which =60.
