parden,

f:s = 7:3,
7x:3x = 756,

x=6,

f:S= 42:18
after 6 years
f:s = 48:24,
f:S = 2:1 ans.

let sons age =y ,fathers age=x,ratio=x/y=7/3,
x*y=756, so y=18 and x=42 so now
42+6/18+6=2:1

the ages are in ratio 7x:3x
father's age 7x
son's age 3x
so product of ages is 7x*3x = 756
so 21x^2=756
x^2 = 36
x = 6
now father's age 7x = 42
son's age 3x = 18
so after 6 years their ages are in ratio 48:24 = 2:1

f:s=7x:3x
given 7x*3x=756
thrfore x=6
f=7*6=42; f+6=42+6=48
s=3*6=18; s+6=18+6=24
f:s=48:24=2:1
