  1. The sum of three consecutive numbers is 87. The middle number is
    1. 27
    2. 29
    3. 30
    4. 28
Correct Option: B

Let us assume the three consecutive natural numbers be N, N + 1, N + 2.
According to the question,
N + N + 1 + N + 2 = 87
⇒  3N + 3 = 87

⇒ 3N = 84 ⇒  N =
84
 = 28
3

∴  Middle number = 28 + 1 = 29
