Two numbers are in the ratio 2 : 3. If their L.C.M. is 48. what is sum of the numbers?
A. 28
B. 40
C. 64
D. 42

• B
  Let the numbers be 2x and 3x
  LCM of 2x and 3x = 6x
  Given that LCM of 2x and 3x is 48
  => 6x = 48
  => x = 48⁄6 = 8
  Sum of the numbers = 2x + 3x = 5x = 5 × 8 = 40

• Let the nos be 2x and 3x.
  So,lcm(2x,3x)=6x
  =>6x=46
  Or x=8.
