Jerry went to a shop and bought things worth Rs. 35, out of which 30 % went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items? | [
"19.7",
"29.7",
"21.3",
"21.5"
] | B | Total cost of the items he purchased = Rs.35
Given that out of this Rs.35, 30 % is given as tax
=> Total tax incurred = 30 % = Rs.30/100
Let the cost of the tax free items = x
Given that tax rate = 6%
∴ (35−30/100−x)6/100 = 30/100
⇒ 6(35 −0.3 −x) = 30
⇒ (35 − 0.3 − x) = 5
⇒ x = 35 − 0.3 − 5 = 29.7
