Question

If the sum of two consecutive natural numbers is 25, then the smaller number is .

• A. $12$
• B. $9$
• C. $6$

Answer 1

The correct option is A $12$

Let the smaller number be $x$,
The, the larger number $=x+1$
Give, the sum of both of these $=25$
$\Rightarrow x+x+1=25$
$\Rightarrow 2x+1=25$
$\Rightarrow 2x=25-1=24$
$\Rightarrow 2x=24$
Dividing with $2$
$\Rightarrow \frac{2x}{2}=\frac{24}{2}\Rightarrow x=12$
