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

Eccentric = Total moment at A/Total loads = 3*2+7*9+10*15 = 219/20 = 10.95 cm.

@Abdul Khan.

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

At hinge point moment is zero. What is the reaction on that point?

3*2 + 7*9 + 10*15 = 20X.
Then, X = 10.95.
