The average age of fifteen persons is 32 years. If two more persons are added then the average is increased by 3 years. The new persons have an age difference of 11 years between them. The age (in years) of the younger among the new persons is:
let the age of younger person is $$x$$ and older person is $$y$$
According to Question
$$\therefore y - x =11$$Â Â
Given that,
initially 15 people are there and their avg. age is 32 yrs .
when $$x$$ and $$y$$ get included then avg. becomes 35 yrs, So
$$\therefore \frac{15\times 32 + x + y}{17} = 35 $$
$$\Rightarrow 15 \times 32 + x + y = 17 \times 35 $$
$$\Rightarrow 480 + x + y = 595$$
$$\Rightarrow x + y =595 - 480 = 115$$
By solving Both Equations, we getÂ
$$\Rightarrow x = 52 $$ yrs
