A number exceeds the other number by 12. If their sum is 72, find the numbers

Solution:

Let the number be x

Then the other number be (x + 12)

A/Q

x + (x + 12) = 72

2x = 72 - 12

x = 60/2

x = 30

Hence, (x + 12) = 42

Thus, the numbers are 30 and 42.

✦ Try This: A number exceeds the other number by 10. If their sum is 86, find the numbers.

Let the number be x

A/Q

x + (x + 10) = 86

2x = 86 - 10

x = 76/2

x = 38

Hence, (x + 10) = 48

Thus, the numbers are 38 and 48.
