Answer 1

Answer......

C is correct

Answer 2

Answer:

Step-by-step explanation:

Explanation:  

Solution 1

Total cost of the items he purchased = Rs.25

Total tax incurred = 30 paise = Rs.30100

Let the cost of the tax free items =x  

Given that tax rate = 6%

∴(25−30100−x)6100=30100

=>6(25−0.3−x)=30

=>(25−0.3−x)=5

=>x=25−0.3−5=19.7

Solution 2

tax = 30 paise = Rs.0.3

tax is 6%.

i.e., Rs.0.3 is 6% of the taxable item.

Therefore, cost of taxable item =0.3×1006=5

cost of the tax free items =25−(0.3+5)=19.7
