Q4 of 33 Page 41

The sum of three consecutive natural numbers is 33. What are the numbers?

Let the three consecutive natural numbers be x,x + 1,x + 2.

Their sum = 33


⇒ x + x + 1 + x + 2 = 33


⇒ 3x + 3 = 33


⇒ 3x = 33-3


⇒ 3x = 30


⇒


⇒ x = 10


⇒ x + 1 = 11


x + 2 = 12


Hence, the three required consecutive natural numbers are 10,11 and 12.
