The answer should be option D.
We get Rs. 5 as the number of taxable items which includes the tax of Rs 0.3.
Then why should we add that tax of Rs. 0.3 again in the last equation as Rs.5 contains the tax of Rs. 0.3 already.
Therefore, the cost of tax-free items should be = Rs.(25-5) = Rs.20.
Hope you all understood.
