Rahul went to a shop and bought things worth Rs. 25, out of which 24 Paise went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items?	Choose the correct choice from the following options:  A) 19  B) 19.7  C) 20.7  D) 21.7  E) 22.8
Total cost of the items he purchased = Rs.25   Given that out of this Rs.25, 24 Paise is given as tax   =&gt; Total tax incurred = 24 Paise = Rs.24/100   Let the cost of the tax free items = x   Given that tax rate = 6%   ∴ (25−30/100−x)6/100 = 24/100   ⇒ 6(25 −0.3 −x) = 24   ⇒ (25 − 0.3 − x) = 4   ⇒ x = 25 − 0.3 − 4 = 20.7   20.7)
