Question

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

Answer 1

Step-by-step explanation:

First number = 2x

Second number = 3x

Hcf = x

LCM = 2x * 3x / x

48 = 6x

6x = 48

x = 8

First number = 2(8) = 16

Second number = 3(8) = 24

Sum of these two numbers = 16+24 = 40
