Question

The H. C. and L. C. M. of two numbers x and y are respectively 3 and 105.If x+y=36 then 1/x+1/y= value of the sum
​

Answer 1

Answer:

1/x+1/y = 36/315 ≈0.114 (approx.)

Step-by-step explanation:

H .C.F of x and y is= 3

L.C.M of x and y is = 105

x+y=36

,', xy = 3 x 105 = 315

,', 1/x+1/y = (x+y)/xy = 36/315 ≈0.114 (approx.)
