Question

Suleman bought eid card at Rs 480 per 100 and sold them at Rs 7 each. What was his percentage gain?

Answer 1

• CP of 100 cards = ₹ 480
• SP of 1 card = ₹ 7
• SP of 100 cards = SP of 1 card × 100

⠀

⠀⟹⠀ ₹ 7 × 100

⠀⟹⠀ ₹ 700

⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀$\sf\bold{Profit = SP - CP}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⟹ ⠀₹ 700 - ₹ 480

⠀⟹ ⠀₹ 220

⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀$\sf {\bold{Profit \: percent = \dfrac{Profit}{Cost \: Price} \times 100}}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀⟹⠀$\sf \dfrac{220}{480} \times 100$

⠀⟹⠀$\sf \dfrac{11}{24} \times 100$

⠀⟹⠀$\sf \: 0.458 {\overline{3}} \times 100$

⠀⟹⠀$\sf 0.46 \times 100$

⠀⟹⠀$\sf 46  \%$

⠀⠀⠀⠀⠀⠀⠀⠀⠀

⠀46% is the profit ( approx)
