The L.C.M. of two numbers is 48. The numbers are in the ratio 2 : 3. Then sum of the number is:  Choices:	A) 28	B) 32	C) 40	D) 53	E) 54

Rationale: "let the numbers be 2 x and 3 x . then , their l . c . m . = 6 x . so , 6 x = 48 or x = 8 . the numbers are 16 and 24 . hence , required sum = ( 16 + 24 ) = 40 . answer : option c"
Answer: C
