Gauri went to the stationers and bought things worth Rs. 25, 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?
Answer: Option
Explanation:
Let the amount taxable purchases be Rs. x.
| Then, 6% of x = | 30 |
| 100 |
 x = |
 |
30 | x | 100 |  = 5. |
| 100 | 6 |
Cost of tax free items = Rs. [25 - (5 + 0.30)] = Rs. 19.70

I need help with these 2 questions:
1) A table and two chairs together cost $400. If by selling the chairs at 10% loss and the table at 10% profit, a total of 5% profit is made. What is the cost price of a chair?
2) A container contains 30 litres of alcohol. From this container 5 litres of liquid is taken out and the container is completely filled by water. Next time 6 litres of mixture was taken out and the container was completely filled with water. Approx how much percent alcohol is left behind in the container?

analyze this way... saletax on tax
6% is 30ps that is saletax on tax so find tax...
if 6%=30ps find for 100% u get tax
non taxable items = cost-tax-saletax = 25 - 5 - .3 = 19.70
6% is 30ps that is saletax on tax so find tax...
if 6%=30ps find for 100% u get tax
non taxable items = cost-tax-saletax = 25 - 5 - .3 = 19.70

Answer has to be option-d. Simply if 2o rs is non-taxable then 5 rs. Is taxable and 6% of that is 30 ps.

Because we have to find the cost of tax free item.
Cost of item on which tax is payed is Rs. 5 and the tax on Rs. 5 is 30 paise.
Cost of tax free items = Rs. [25 - (5 + 0.30) ] = Rs. 19.70.
Have a nice day!

Why do we add that 0.30 at the last part? Didn't understand.
25- (5+. 30)
25- (5+. 30)

Hi Karthik,
We can write 30 paise as Rs. 0.30 or Rs. 30/100.
