Answer:

It is at a distance of #1.143# #m.# from fulcrum

Explanation:

For a balance lever moments of the two forces must be equal. Moment is given by the product of weight and its distance from fulcrum.

Moment of first weight is #8xx5=40# #kg.m#. as the second weight weighs #35# #kg.#,

it is at a distance of #40/35=1.143# #m# from fulcrum.
