Rahul went to a shop and bought things worth Rs. 30, 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?
Answers:
A) 25.7
B) 24.7
C) 23.7
D) 22.7
E) 26.7
Total cost of the items he purchased = Rs.30   Given that out of this Rs.30, 30 Paise is given as tax   =&gt; Total tax incurred = 30 Paise = Rs.30/100   Let the cost of the tax free items = x   Given that tax rate = 6%   ∴ (30−30/100−x)6/100 = 30/100   ⇒ 6(30 −0.3 −x) = 30   ⇒ (30− 0.3 − x) = 5   ⇒ x = 30 − 0.3 − 5 = 24.7   24.7)
