To calculate the amount of sale, let the sale amount be x

The sales tax is 4% of  x, and it is given as Rs 2. Therefore:

4% of x

(4/100)*x=2

x= (2*100)/4

Thus, the amount of sale is 50

If the sales tax of 4 percent on an article amounts to Rs 2, you can calculate the sale amount by dividing the tax by the tax rate.

So, Rs 2 divided by 0.04 equals Rs 50. This means the sale price before tax is Rs 50.

Adding the Rs 2 tax gives a total of Rs 52, which is the price after tax.

Let amount of sale be x

4 % of sales tax on X is 2

4*x/100= 2

x = 2*100/4

x = 50
