Question

Manish and Nitish are brothers. Manish is three years younger than Nitish. If Nitish age is $x$ then Manish’s age could be represented by the algebraic expression.
$\left[2Marks\right]$

Answer 1

Given that Manish is three years younger than Nitish. so, Manish's age is always three years less than Nitish's age.

For example,
If Nitish’s age is 12 years, his brother’s age would be 12 - 3 = 9 years.
$\left[1Mark\right]$

So, if Nitish’s age is $x$, then the expression for Manish’s age would be $(x-3)$.
$\left[1Mark\right]$
