First S.P = ₦230.00
% profit = 15%
% profit = S.P−C.PC.P x 100%
⇒ 15% = 230−C.PC.P x 100%
⇒ 15100=230−C.PC.P
⇒15C.P = 100 (230 - C.P)
⇒15C.P = 23000 - 100C.P
⇒15C.P + 100C.P = 23000
⇒115C.P = 23000
⇒ C.P = 23000115 = ₦200.00
Second S.P = ₦180.00
Since C.P is greater than S.P, therefore it's a loss
% loss = C.P−S.PC.P x 100%
⇒ 200−180200 x 100%
⇒ 20200 x 100%
⇒ 110 x 100% = 10%
∴ It's a loss of 10%
