Find the fourth proportional to m + 3, m + 7 and 15m if m = 3

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 75.

First term (a) = m + 3 = 3 + 3 = 6

Second term (b) = m + 7 = 3 + 7 = 10

Third term (c) = 15m = 15 × 3 = 45

Fourth Proportion = (b × c)/a = (10 × 45)/6 = 75
