Question

The sum of two numbers is $30$. One of the number exceeds the other by $10$. Find the number.

• A. $10,-20$
• B. $-10,20$
• C. $10,20$
• D. $-10,-20$

Answer 1

The correct option is C $10,20$

Let the required number be $x$.
Then, the other number will be $x+10$
According to the question, sum of the two numbers is $30$.

Therefore, $x+x+10=30$
$\therefore 2x=20$
$\therefore x=10$
The numbers are $10$ and $10+10=20$.
