### Question

The sum of three consecutive even integer numbers is 672. The middle among the three is?

**A**

224.

**B**

225.

**C**

223.

**D**

226.

**Soln.**

**Ans: a**

Let the numbers be 2n - 2, 2n and 2n + 2. The sum is 6n = 3 x 2n = 3 x middle. We are given 3 x middle = 672, ⇒ middle = $672/3$, i.e., middle = 224.
