Answer 1

Answer   : 'c"

Step-by-step explanation:

let arun age be = x

let bharath age be= y

let chandan age be = z

1)  x+y =86

2) y+z=73

3) x+z=15

from eq. 1 and 2        x + y =86

                                   z + y =73

                               __-__-__-___

                               x-z = 13----------(4)

now compare eq. 4 and 3

                      x=14

now substitute this value in eq. 1 and find other age
