Answer 1

Answer:

Age of son = 7 yrs

Age of father = 40 yrs

Step-by-step explanation:

Let the age of man be 'x' years and let the age of son be 'y' years

∴ from first condition ,

x + y = 47  --------(1)

Age of man after 4 years = ( x + 4 ) years

Thus , from second condition ,

x + 4 = 4(y+4)

∴ x + 4 = 4y + 16

∴ x = 4y + 12 ----------(2)

Solving (1) and (2) , we get

x = 40 and y=7
