@Abdul Khan.

Point A is hinged that's why the moment about A is zero.

They have found the Resultant force acting distance from A. So, the rod will balance where resultant force acting only that point.

Balanced distance = summation of moments/summation of loads.
d = 219/20,
= 10.95.

The answer is 10.95 cm from A.

Explanation : The ratio of the moment about A to the total load.
Answer : 10.95cm.

That's not complex+> explanation/blanced point which the point have equlibrim eq sum of force equla 0 force * (x-dis) = zero.
