alisha goes to a supermarket and bought things worth rs 60 out of which 40Ps went on sales tax.if tax rate is 10% then what was cost of tax free items?

What does Ps mean?.

To find the cost of the tax-free items, we need to subtract the amount spent on the sales tax from the total purchase cost.

First, let's calculate the sales tax amount:
Sales Tax = Total Purchase Cost * Tax Rate
Sales Tax = Rs 60 * 10/100
Sales Tax = Rs 6

Now, we can find the cost of tax-free items:
Cost of Tax-Free Items = Total Purchase Cost - Sales Tax
Cost of Tax-Free Items = Rs 60 - Rs 6
Cost of Tax-Free Items = Rs 54

Therefore, the cost of the tax-free items is Rs 54.
