Question

The L.C.M. of two numbers is 48. The numbers are in the ratio 2:3. Then sum of the numbers is:

• A. 16
• B. 40
• C. 32
• D. 28

Answer 1

The correct option is B

40

Let the numbers be 2xand 3x.

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

So, 6x= 48 orx= 8.

The numbers are 16 and 24.

$\Rightarrow$ The numbers are 16 and 24

$\Rightarrow$ Hence, required sum = (16 + 24) = 40
