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 the nearest integer) he would get on buying a dozen articles?
A man buys a single article at ₹16.
1 dozen = 12 article
Price of 12 articles = $$12\times16$$
= ₹192
But he paid ₹160 for one dozen(12) articles.
discount percent = $$\frac{\left(192-160\right)}{192}\times100$$
= $$\frac{32}{192}\times100$$
= 16.67%
= 17% approx.
