Three quantities are in the ratio 4 : 9 : 16. If their sum is 174, find the second quantity.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 54
Let the quantities be 4x, 9x and 16x. Their sum is 29x = 174, so x = 6.
The second quantity is 9x = 9 × 6 = 54; the other two are 24 and 96, and 24 + 54 + 96 = 174.
