Question

5. A shopkeeper buys an article for 450. He
marks it at 20% above the cost price. Find :
(i) the marked price of the article.
(ii) the selling price, if he sells the article at
10 percent discount.
(iii) the percentage discount given by him, if he sells the article for 496.80.​

Answer 1

Step-by-step explanation:

cost price of the article = 450

i) 20%above cost marked price = 450+20% = 540

iii) % of discount = (540-496.80)/100 = 92%

ie. 100-8= 92

Therefore discount % = 8%

540 - 8% = 496.8

Answer 2

i} Profit=20/100*450--------->Profit=Rs. 90

MP=CP+Profit---------->MP=450+90---------->MP=Rs. 540.

ii} SP=MP(100-D%)/100-------->SP=540*90/100--------->SP=Rs. 486.

iii} Discount=MP-SP---------->Discount=540-496.80---------->Discount=Rs. 43.20

Discount%=D/MP*100--------->Discount%=43.2/540*100

Discount%= 8%
