According to the given question
L.C.M. of two numbers = 3
H.C.F of two numbers = 105
Then,
L.C.M. × H.C.F. = 3 × 105
X × Y = 3 × 105

[Because we know that, If X and Y are two numbers then
(L.C.M. of X and Y) × (H.C.F. of X and Y) =X × Y]
X × Y = 315 ______________ (1)
Also given in the question

X + Y = 36 _______________ (2)

( X + Y )/(X × Y) =36/315

X/(X × Y) + Y/(X × Y) = 36/315

1/Y + 1/X = 4/35

1/X + 1/Y = 4/35
Hope this helps you

Answer: 4/35

Step-by-step explanation:

1/x + 1/y

= (y + x) / xy

= 36/(3*105). [we know that product of two numbers is equal to the product of their LCM and HCF]

= 4/35
