Question

Sum of two numbers is 15. One of the numbers is 5 more than the other. What is the correct equation representing the above statement?

• A. x + (x + 5) = 15
• B. x + 15 = 15
• C. x+ (x-5) = 15
• D. Both A and C

Answer 1

The correct option is D

Both A and C

If the smaller number is taken to be x the larger number is 5 more than x, i.e. x + 5 the other condition says that sum of these two numbers x and x + 5 is 15

This means that x + (x + 5) = 15

Similarly, if the large number is taken as x, then the smaller number will be x - 5. So the equation will be

x + (x - 5) = 15
