Answer:
5%
Step-by-step explanation:
Correction in the question : 10% discount is only once
Market price of a watch is Rs.1200.The shopkeeper gives a discount of 10% then gives a successive discount on the reduced rate again.The customer had paid only Rs.1026.
Market Price = Rs 1200
After First Discount = 1200 - (10/100)1200 = 1080
Then He says D % Discount then
Price = 1080 - (D/100)1080 = 1026
= > 1080 * 100 - 1080D = 1026*100
=> 1080D = 100(1080 - 1026)
=> 108 D = 10 ( 54)
=> D = 10 /2
=> D = 5 %
