C, 1783.40
Correct AnswerA, 1735.20
Incorrect AnswerExplanation:
- Shopkeeper A applies two successive discounts of 20% each on the marked price of Rs 4820.
- First discount = 20% of 4820 = Rs 964
- Price after first discount = 4820 - 964 = Rs 3856
- Second discount = 20% of 3856 = Rs 771.20
- Final price = 3856 - 771.20 = Rs 3084.80
- Total discount = 4820 - 3084.80 = Rs 1735.20
- Shopkeeper B gives discounts of 25% and then 15%.
- First discount = 25% of 4820 = Rs 1205
- Price after first discount = 4820 - 1205 = Rs 3615
- Second discount = 15% of 3615 = Rs 542.25
- Final price = 3615 - 542.25 = Rs 3072.75
- Total discount = 4820 - 3072.75 = Rs 1747.25
- Shopkeeper C applies discounts of 30% and then 10%.
- First discount = 30% of 4820 = Rs 1446
- Price after first discount = 4820 - 1446 = Rs 3374
- Second discount = 10% of 3374 = Rs 337.40
- Final price = 3374 - 337.40 = Rs 3036.60
- Total discount = 4820 - 3036.60 = Rs 1783.40
Option 2, C: Rs 1783.40 is correct
