What will be the sum of third proportional to 18 and 54 and fourth proportional to 12, 18 and LCM of 12 and 18?
Solution
Correct Answer: Option B
Third proportional to 18 and 54 will be (54 × 54)/18 = 162
LCM of 12 and 18 is 36.
Fourth proportional to 12, 18 and 36 will be (36 × 18)/12 = 54
∴ Sum = 162 + 54 = 216
