Problem

The larger of two consecutive odd integers is three times the smaller. What is their sum?

\text{(A)}\ 4 \qquad \text{(B)}\ 8 \qquad \text{(C)}\ 12 \qquad \text{(D)}\ 16 \qquad \text{(E)}\ 20

Solution

Let the two consecutive odd integers be a, a+2. Then a+2 = 3a, so a = 1 and their sum is 4\ \mathrm{(A)}.
