Question

If the sum of two whole numbers is 24 more than their difference, then one of the number must be

a) 0 b) 6 c) 12 d) 48

Answer 1

Option C. 12

Explanation:

Let

x---> one whole number

y ---> the second whole number

we know that

x+y=(x-y)+24

`x-x+y+y=24\\2y=24\\y=12`

therefore

One of the number must be 12
