Question

The sum of
ages of son and father is 56 years. After four years the age of
the father will be thrice the son's age. Find their ages.​

Answer 1

Step-by-step explanation:

s+f =56

f=56-s

f+4 =3(s+4)

f+4 = 3s+12

56-s +4 = 3s+12

60-12 = 4s

s = 48/4 = 12

f= 56-12 = 44

Answer 2

Let the son age after 4 years be x+4
Then father’s age after four year be 3x+4

X+4+3x+4=56
4x+8=56
4x=56-8
4x=48
X=48/4
X=12

Father’s present age = 3x=3*12=36

Son’s present age =x=12
