Answer:

D. 7

Explanation:

To find out the lesser number, we can go off the given information 3 less than of the other number, meaning we can add three to each answer choice to find the second number and see if those numbers have a sum of 17.

3 + 3  = 6
6 + 3 = 9
incorrect

5 + 3 = 8
8 + 5 = 13
incorrect

12 + 3 = 15
15 + 12 = 27
incorrect

7 + 3 = 10
10 + 7 = 17
correct

Thus, the answer is D.

hope this helps!
