Question

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

Answer 1

Let x be a number, then another number will be x + 12

According to the question,

x + x + 12 = 72

⇒ 2x = 72 – 12  ...[Transposing 12 to RHS]

⇒ 2x = 60

⇒ x = 30  ...[Dividing both sides by 2]

Hence, the numbers are 30 and (30 + 12) i.e. 30 and 42.
