Q69 of 107 Page 104

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

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


According to the question,


x + x + 12 = 72


⇒ 2x + 12 = 72


⇒ 2x = 72 – 12


⇒ 2x = 60


⇒ x = 30


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