Question

Sanju is $6$ years older than his brother Nishu. If the sum of their ages is $28$ years, what are their present age ?

Answer 1

Let the age of Nishu be $x$ years.

Then, age of Sanju will be $x+6$ years.

Given, Sum of their ages is $28$

Therefore, $x+x+6=28$

$2x=28-6$

$\Rightarrow x=11$

Thus, age of Nishu is $11$ years.

Now, age of Sanju will be $x+6=11+6=17$ years.
