1. If the sum of 3 consecutive integer is 210, then the sum of the two smaller integer is-
- A. 139
- B. 139
- C. 139
- D. 139
Answer: Option A
Explanation:
Let the integers be X, X + 1 and X + 2 respectively.
Then, X + X + 1 + X + 2 = 210
or, 3X + 3 = 210
or, 3X = 210 - 3 = 207
or, X = 207/3 = 69
Then, sum of the two smaller integers = X + X + 1 = 69 + 69 + 1 = 139.
