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 reciprocal of the numbers is equal to:
Choose the correct choice from the following options:
A) 55/601	B) 601/55	C) 11/120	D) 120/11	E) 120/13
Let the numbers be a and b.   Then, a + b = 55 and ab = 5 * 120=
