Answer 1

let the father be x

let the daughter be y,

seven years back,

aftab=x-7

daughter=y-7

(x-7)=7(y-7)[give in question]

x-7=7y-49

x-7y=-42........(1)

Three years after,

aftab=x+3

daughter=y+3

x+3=3(y+3)

x-3y=6........(2)

from 1 and 2,

x-7y=-42

x-3y=6

(-) (+) (-)

________

-4y=-48

y=12

daugther=12

x=6+36=42

father=42
