Question

Average age of a father and his son is 22 years .Ratio of their age is 10:1 ,what is the age of the son?

Answer 1

Answer:4years

Step-by-step explanation:

Let the age of father be 10x and son x

(10x+x)/2=22[Average age]

11x=44

x=4

Age of son is 4 years..

Answer 2

Let,

Father's age = 10x years

Son's age = x years

Now,

( Father's age + Son's age ) / 2 = 22

Father's age + Son's age = 44

10x + x = 44

11x = 44

x = 44 / 11

x = 4

Their ages :

Father's age = 10x = 10 ( 4 ) = 40 years

Son's age = x = 4 years
