Correct option is A
Given:
Selling price(SP)= Rs. 540
Formula used:
AT loss%
Cost price (CP) = SP x (100/(100- loss%))
Selling price = CP (100- Loss%)/100
Calculation:
SP of the goods = Rs. 540
=> CP of the goods = 540 x 100/90 = Rs. 600
New SP of the goods at 5 % loss
Rs. 600 x 95/100
=> Rs. 570
selling price is Rs. 570.
