A shopkeeper was offering two successive discounts of 20% and 15% on an item whose marked price is 1,000, while
another shopkeeper was offering a flat 33% discount on the same item. Find the positive difference in the nominal
amounts of discounts given by the two shopkeepers on the sale of the item.

'एक दुकानदार एक वस्तु, जिसका अंकित मूल्य ₹1,000 है, पर 20% और 15% की दो क्रमागत छूटें दे रहा था, जबकि दूसरा दुकानदार
उसी वस्तु पर 33% की एकल छूट दे रहा था। वस्तु की बिक्री पर दोनों दुकानदारों दूवारा दी गई छूट की धनराशि का धनात्मक अंतर
ज्ञात कीजिए।


Options

A

B

C

D


Solution:

Correct Answer:

D


Marked price for both the shopkeepers = 1000

Discount percentage after two successive discounts of 20% and 15% = 20 + 15 - 20×15100\frac{20\times15}{100}

Discount = 35 - 3 = 32%

Another shopkeeper's discount percentage = 33%

Diffrence discount percentage = 33 - 32 = 1%

Amount of discount diffrence = 1% of 1000 = 10

दोनो दुकानदारो के लिए अंकित मूल्य  = 1000

20% और  15% के दो क्रमागत छूटों को मिलाकर दी गयी छूट = 20 + 15 - 20×15100\frac{20\times15}{100}

छूट = 35 - 3 = 32%

दूसरे दुकानदार द्वारा दी गयी छूट =  33%

 दोनो छूटों का अंतर = 33 - 32 = 1%

 छूट की धनराशि का धनात्मक अंतर = 1% of 1000 = 10
