The L.C.M. of two numbers is 36. The numbers are in the ratio 2 : 3. Then sum of the number is: Choose the correct choice from the following:  A) 28  B) 30  C) 40  D) 53  E) 54
Let the numbers be 2x and 3x.   Then, their L.C.M. = 6x.   So, 6x = 36 or x = 6.   The numbers are 12 and 18.   Hence, required sum = (12 + 18)=
