Gauri went to the stationers and bought things worth Rs. 25, out of which 30 paise went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items?

[A].	Rs. 15
[B].	Rs. 15.70
[C].	Rs. 19.70
[D].	Rs. 20

Answer: Option C

Explanation:

Let the amount taxable purchases be Rs. x.

Then, 6% of x =	30
	100

x =		30	x	100	= 5.
		100		6

Cost of tax free items = Rs. [25 - (5 + 0.30)] = Rs. 19.70
