1.  The L.C.M. of two numbers is 48. The numbers are in the ratio 2 : 3. Then sum of the number is:
A. 28
B. 32
C. 40
D. 64

Answer: Option C

Explanation:

Let the numbers be 2x and 3x.

Then, their L.C.M. = 6x.

So, 6x = 48 or x = 8.

The numbers are 16 and 24.

Hence, required sum = (16 + 24) = 40.
