A man buys a single article at ₹16. If he were to buy a dozen articles, he would have to pay a total amount of ₹160. What would be the approximate percent discount (correct to nearest integer) he would get on buying a dozen articles?
Answer & explanation
Correct answer: option 2
A single article can be bought at = 16
If a dozen article he bought he has to give = 160
According to question
Cost of one article = Rs. 16
Cost of 12 articles = 16 × 12 = Rs. 192
But he gave Rs. 160
Hence, discount = 192 – 160 = 32
Discount percentage = \(\frac{32}{192}\) × 100 = 16.66% = 17%
