a. 10
b.20
c.30
d.40
e.50

Answer 1

d. 40

Explanation:

Immediately, c. 30 and e. 50 can be eliminated because 20 is not a factor of these numbers. Now, factoring the other numbers, 40 is the only number that matches the question criteria. Although 20 is a factor of 10, 20, and 40, only 40 is greater than 30; hence, 40 is the answer.
