Correct option is A
Given:
Marked Price = 10% above Cost Price
Discount Allowed = 10%
Formula Used:
Selling Price =Marked Price×(1−100Discount)
Profit % = (CPSP−CP)×100
Solution:
Let Cost Price = ₹100
Then, Marked Price = ₹100 + 10% of ₹100 = ₹110
Selling Price = ₹110 ×(1−10010)=₹110×0.90=₹99
Loss = ₹100 - ₹99 = ₹1
Loss % = (1001)×100=1%
Alternate Method:
Loss % =100x1x×100 = 1%
