The sum of three consecutive odd natural numbers is 87. The smallest of these numbers is :

1. 29
2. 31
3. 23
4. 27

Correct Option: D

Let us assume the 3 odd consecutive natural numbers be P, P + 2 and P + 4.
∴ According to the given question
P + P + 2 + P + 4 = 87
⇒ 3P + 6 = 87
⇒ 3P = 81
⇒ ∴ P = 27
∴ Smallest number = 27
