Solution

x + (x +2) = 70 => x = 34
Numbers are 34 and 36; sum of their squares is 1156 + 1296 = 2452

x+2x+2=70 2x=70 x=70-2/2=34
34*34=1156 36*36=1296
1156+1296=2452

Ages are x and x+2, then 2x+2=70, x=34;
34+36=70 and 34^2+36^2= 2452

SUDESHNA SEN   14 years AGO

Let the ages be x and x+2 years.
So, x+x+2= 70,
or x= 34 and x+2= 36.
Therefore, their ages are 34 years and 36 years and sum of squares of their ages are= 34^2+36^2= 2452..... Option 9)
