Answer Let , the present age of a man = x years

and the present age of his son = y years

According to the question ,

x = 5y and x +2 = 4 ( y + 2 )

: * x + 2 = 4 ( y + 2 )

5y +2 = 4y + 8

= 5y - 4y = 8 - 2

y = 6

Hence ,

x = 5y = 5 ( 6 ) = 30

i.e. , the present age of a man = 30 years and the present age of his son = 6 years

Answer:

Let, the present age of a man =x years

and the present age of his son =y years

According to the question,

x=5y and x+2=4(y+2)

∵x+2=4(y+2)

⟹5y+2=4y+8

⟹5y−4y=8−2

∴y=6

Hence, x=5y=5(6)=30

i.e., the present age of a man =30 years

and the present age of his son =6 years
