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

Let the cost of tax free items be Rs. X.
then, the cost of taxable items equals Rs. 25-x.
Therefore, 6% of 25-x = 0.3,
6/100(25-x) = 0.3,
X = 20.
then, the cost of taxable items equals Rs. 25-x.
Therefore, 6% of 25-x = 0.3,
6/100(25-x) = 0.3,
X = 20.

The answer is D becuase;
Given,
Total cost = Rs25 = Cost of non-taxable items + cost of taxable items = NT + T ----> eq.1
Now,
6% of cost of taxable items = Rs0.3.
Therefore, cost of taxable items = (100*0.3)/6 = Rs 5 = T.
From eq.1,
25 = NT + T.
25 = NT + 5.
Therefore, Cost of non-taxable items = Rs20 ----> Ans: D.
Given,
Total cost = Rs25 = Cost of non-taxable items + cost of taxable items = NT + T ----> eq.1
Now,
6% of cost of taxable items = Rs0.3.
Therefore, cost of taxable items = (100*0.3)/6 = Rs 5 = T.
From eq.1,
25 = NT + T.
25 = NT + 5.
Therefore, Cost of non-taxable items = Rs20 ----> Ans: D.

Hi Karthik,
We can write 30 paise as Rs. 0.30 or Rs. 30/100.
Have a nice day!

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

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.

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.
