The selling price of a desktop is 9 times of the profit earned on selling this desktop. What is the profit percentage?
Answer & explanation
Correct answer: option 2
The selling price of a desktop is 9 times of the profit earned on selling this desktop.
SP = 9(SP-CP)
SP = 9SP-9CP
9CP = 9SP-SP
9CP = 8SP
\(\frac{CP}{SP}\) = \(\frac{8}{9}\)
Profit % = (9 – 8) × \(\frac{100}{8}\) = 12.5%
