Take the age of dad as 10x

take the age of son as 1x

average = addition of the observations/Total observation

10x+x/2=22

11x\2=22

11x=44

x=4

SON IS 4 YEARS OLD

THX!!!!

उत्तर : -

पिता और उसके पुत्र की औसत आयु = 22 वर्ष

उनकी आयु का अनुपात  = 10:1

माना पिता की आयु = 10x

और पुत्र की आयु = 1x

\starजैसे कि हमें ज्ञात है =

औसत = समस्त राशियों का योग/राशियों की संख्या

\sf{\implies}\dfrac{10x + 1x}{2}=22

\sf{\implies}\dfrac{11x}{2}=22

\sf{\implies}11x = 22 \times 2

\sf{\implies}11x = 44

\sf{\implies}x = \dfrac{44}{11}

\sf{\implies}x = 4

पुत्र की आयु = 4 वर्ष

पिता की आयु = 10x

\sf{\implies} 10 × 4

\sf{\implies} 40

पिता की आयु = 40 वर्ष

पुत्र की आयु = 4 वर्ष

\textsf{\large{Solution In English :-}}

Given :

Average of the ages of son and father = 22 years

The Ratio of their ages = 10 : 1

To find :

The age of the son

Solution :

Consider the age of father as 10x

Consider the age of son as x

\star As we know :

\boxed{\sf{Mean \:= \frac{Sum \: of \: Observations}{No.of \: Observations} }}

\sf{\implies}\dfrac{10x + 1x}{2}=22

\sf{\implies}\dfrac{11x}{2}=22

\sf{\implies}11x =22 \times 2

\sf{\implies}11x = 44

\sf{\implies}x =\dfrac{44}{11}

\sf{\implies}x = 4

The age of son is 4 years

Value of 10x

\sf{\implies} 10 × 4

\sf{\implies} 40

\therefore The age of father is 40 years and the age of the son is 4 years.
