The LCM of two numbers is 48. The numbers are in the ratio 2: 3. The sum of the numbers is |
A) 28
B) 32
C) 40
D) 64
Correct Answer: C
Solution :
If the numbers are 2x and 3x. |
Then, LCM of 2x and \[3x=6x\] |
LCM = 48 [given] |
\[\therefore \] \[6x=48\]\[\Rightarrow \]\[x=\frac{48}{6}=8\] |
So, total numbers are \[(8\times 2=16)\] and \[(8\times 3=24),\] respectively. |
\[\therefore \] Sum \[=16+24=40\] |
