Answer 1

Marked price of the watch = Rs. 5250

Step-by-step explanation:

The selling price of a watch is Rs.2100 after giving three successive

discounts of 20%, 33.33%, and 25%.

(i) Selling price = 2100

 Discount = 25%

CP - 25% of CP = 2100

 CP (100 - 25) = 210000

 CP = 210000 / 75

 CP = 2800

(ii) SP = 2800

Discount = 33.33%

CP - 33.33% of CP = 2800

 CP (100 - 33.33) = 280000

 CP = 210000 / 66.67

CP = 4200

(iii) SP = 4200

Discount = 20%

CP - 20% of CP = 4200

 CP (100 - 20) = 420000

 CP = 420000 / 80

 CP = 5250

So the actual marked price before the 3 successive discounts was Rs. 5250.
