An article is marked at Rs.7,500 and available at a discount of 12%. The shopkeeper gives another off-season discount to the buyer and sell the article for Rs.5,400. Find the off-season discount. (Correct to two decimals places.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 18.18%.
M.P. = Rs.7500
Initial C.P. after 12% discount = 7500 × 88/100 = Rs. 6600
Let x be the final discount
Final S.P. = 6600 - 6600 × x/100 = 6600 - 66x
Final S.P. = Rs.5400
⇒ 5400 = 6600 - 66x
⇒ 66x = 6600 - 5400
⇒ 66x = 1200
⇒ x = 18.18%
