Rahul went to a shop and bought things worth Rs. 55, 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?
Choose the correct choice from the following answers:	A) A)19.7	B) B)19.9	C) C)21.9	D) D)40.9	E) E)49.7
Total cost of the items he purchased = Rs.55   Given that out of this Rs.55, 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%   ∴ (55−30/100−x)6/100 = 30/100   ⇒ 6(55 −0.3 −x) = 30   ⇒ (55 − 0.3 − x) = 5   ⇒ x = 55 − 0.3 − 5 = 49.7   49.7)
