Correct Answer - Option 3 : 66.66%
Formula -
Profit = Selling Price (S.P) - Cost Price (C.P)
% Profit = (Profit × 100) ÷ C.P
Calculation -
⇒ C.P = (60 × S.P) ÷ 100
⇒ or C.P ÷ S.P = 60 ÷ 100
⇒ C.P ÷ S.P = 3 ÷ 5
⇒ C.P = 3, S.P = 5
Profit = 5 - 3
⇒ Profit = 2
% Profit = (2 × 100) ÷ 3
⇒ % Profit = 200 ÷ 3
⇒ % Profit = 66.66%
∴ The required answer is 66.66%
