Question

pls solve this question

Answer 1

Let the two numbers be a and b ,

Given, a=7+b              .................Eq.(1)

and a^2=77+b^2        ..................Eq.(2)

Squaring the Eq.(1) we get

a^2=49+14b+b^2       ..................Eq.(3)

Subtracting Eq.(2) from Eq.(3)

=>0=-28+14b

=>b=2

So from Eq.(1)

a=7+2=9

Thanks!!!
