Shikha is 3 years younger than her brother Ravish. If the sum of their ages is 37 years, what are their present ages?
Given :
Shikha is 3 years younger than her brother Ravish.
The sum of their ages $=$37 years.
To do :
We have to find their present ages.
Solution :
Let the age of Shikha be x.
This implies,
The age of Ravish $= x+3$
Therefore,
$x+(x+3) = 37$
$2x+3 =37$
$2x = 37-3$
$2x = 34$
$x=\frac{34}{2}$
$x=17$
Age of Ravish $= 17+3 = 20$
The age of Shikha is 17 years and the age of Ravish is 20 years.
