Question

4 year ago father age was four times that of son is age.at present the sum of father's age and son age is 53 year what is father's present age. ​

Answer 1

Answer:

Step-by-step explanation:

Let present age be x.

4 years ago

x - 4 = 4(y-4)

x-4 = 4y - 16

x = 4y - 12

x+y = 53

4y-12+y = 53

5y = 65

y = 13

Son's age = 13 years

Father's age = 53-13 = 40 years
