Answer» Answer: Option 2 i.e. 25% Step-by-step explanation: Let CP = 100 Therefore as Profit % = 12.5 % SP = CP x (100+12.5)/100 = 112.5 Discount = 10% (Given) Therefore MP i.e. MARKED price = (112.5 x 100) /90 [As MP x (100-Discount %) / 100 = CP] Therefore Marked price = 125 If discount= 0 then SP = MP Therefore P% = [(SP - CP) x 100 ] / 100 = (125 - 100 /100) x 100 = 25 % |
