Question

please guys solve this question very important tomorrow is my exam guys please help me

Answer 1

f = Father's age now

s = Son's age now

f-20 = Father's age 20 yrs ago

s-20= Son's age 20 yrs ago

WHAT WE HAVE F = 2S

F-20  = 12*(S-20)

F-20 = 12S - 240

12S -  F = 220

SUBSTITUTING

12S - 2S = 220

10S = 220

S = 22

SINCE F = 2S

F = 2*22

F = 44

Father's age = 44

Son's age = 22

Hope You Understand

Cheers!!!
