A teenager's age increased by 2 gives a perfect square Her age decreased by 10 gives the square root of that perfect square She is 5 years older than her brother How old is her brother?

Answer 1

Answer: Her brother is 9 and she is 14.

say she is 14, 14+2=16 a perfect square.

14-10=4 which is the square root of 16.

So she is 14 and her brother is 9.

(He is a perfect square too, by the way.)
