Question

A shopkeeper allows a discount of 10 % to his customers and still gains 20 %. Find the marked price of an article which costs ₹ 450 to his shopkeeper.​

Answer 1

Answer:

Rs.600

Step-by-step explanation:

Here, r = 10% and R = 20%

Therefore, Required per cent = (r+R100−r)×100

= 10+20100−10×100%=30×10090%=1003%

This shows that the marked price of the

item is 1003% more than its cost price.

Now, cost price of the article = Rs.450

Therefore, Marked price of the article = 450×400300 = Rs.600
