Question 70
A shopkeeper allows 10% discount on the marked price of an article and still makes a profit of 8%. If the marked price is ₹480, then what is the cost price (in ₹)of the article?
Solution
If the marked price is ₹480.
A shopkeeper allows 10% discount on the marked price of an article.
Selling price = 480 of (100-10)%
= 480 of 90%
= 432
profit = 8%
(100+8)% of Cost price = 432
108% of Cost price = 432
Cost price = $$\frac{432}{108}\times\ 100$$
= ₹400
