Answer 1

1.1 sons I don't know it may be

Answer 2

Answer:

Age of father is 40 years

Age of son is 4 years

Step-by-step explanation:

Let the age of father be ' x ' years

And age of son be ' y ' years

According to question,

Average age of father and son is 22 years, that is,

( x + y) / 2 = 22

x + y = 22 *2

x + y = 44

x = 44 - y [ Let this be Eqn 1 ]

Also, it is given

Ratio of their age 10 : 1 ,that is,

x : y = 10 : 1

x / y = 10 / 1

x = 10y

Substituting value if x from Eqn 1 ,

44 - y = 10y

44 = 10y + y

44 = 11y

Dividing both the sides by 11

44 / 11 = 11y / 11

y = 4

Substituting value of y in Eqn 1

x = 10y

x = 10 ( 4 )

x = 40

Hence,

Age of father is 40 years

Age of son is 4 years
