If the sum of two numbers is 55 and the H.C.F. and L.C.M. of these numbers are 5 and 120 respectively, then the sum of the reciprocals of the numbers is equal to: Choose the correct choice from the following:	A) 11 / 122	B) 11 / 120	C) 11 / 121	D) 11 / 140	E) 11 / 111

Rationale: explanation : let the numbers be a and b . then , a + b = 55 and ab = 5 x 120 = 600 . the required sum answer : b ) 11 / 120
Answer: B
