Question

Ajay is younger than Vijay by $5$ years. Sum of their ages is $25$ years. What is the Ajay's age ?

• A. $20$
• B. $15$
• C. $10$
• D. $5$

Answer 1

The correct option is C $10$

Solution:- (C) $10$

Let the age of Ajay be $x$.

$\therefore$ Age of Vijay $=x+5$

Now according to the question-

$\left(x\right)+(x+5)=25$

$\Rightarrow x+x+5=25$

$\Rightarrow 2x+5=25$

$\Rightarrow 2x=25-5$

$\Rightarrow x=10$

Hence Ajay's age is $10$ years.
