Answer 1

Answer:

Let

Father's age=X

Son's age=Y

X=5Y---------(1) EQ

4 years back,

Father's age son's age

X-4 = (Y-4) 9

X-4 =9Y-36

X-4-9Y+36=0

X-9Y+32=0

X-9Y = -32-----------(2)EQ

Substitute

X=5Y

In eq no 2

X-9Y = -32

5Y-9Y = -32

-4Y = -32( - gets cancelled)

4Y = 32

Y = 8

X = 5Y

X=5(8)

X=40

Therefore father's age is 40 and his sons age is 8
