Question

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: op

Answer 1

Step-by-step explanation:

we know, the product of two numbers = H.C.F. × L.C.M. of those numbers.

So the product = 5×120=600.

Let two numbers be x and y.

Two eqn. forms:

x+y = 55

xy = 600

you have to find 1/x+1/y
