Solution :
Given
= weight of the first side
= 6 kg = 6000 g
= distance of the first weight from the triangle.
= 3 m = 300 cm
= distance of the first weight from the triangle.
= 600 cm
Let, 
= weight of the second side
So, x = x
or 
= 3000 g
Therefore, the quantity that is used to replace the question mark in order to make the scale balance is 3000 g.
