Practice the questions given in the worksheet on finding value of a percentage.
We know, to find how much per cent one quantity is of another; suppose the value of x % of a quantity be y
The value of x % = y
Therefore, the value of 1 % = y/x
The value of 100 % = y/x × 100
Thus, the value of quantity = y/x × 100
Thus, the value of a quantity when the
value of its certain percent is known = (given value/given percentage) × 100
