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: Choices:
A) 55/601 B) 601/55 C) 11/120 D) 120/11 E) 120/13
given a+b=55,hcm and lcm is 5 and 120   axb=lcmx hcf   600=120x5   1/a+1/b=a+b/ab=&gt;55/600=&gt;11/120   ANSWER:11/120
