Question

If the sum of two numbers is 15 and their difference is 5. Find the two numbers.

• A. $10,5$
• B. $12,3$
• C. $8,7$
• D. None of these

Answer 1

The correct option is A $10,5$

Let the two numbers be x and y. Then,

$x+y=15$ .......(1)

$x-y=5$ .......(2)

Adding equation 1 and 2, we get,

$2x=20$

$x=10$

Thus, $y=5$

Hence, the required numbers are $10$ and $5$.
