Answer 2

Given :

A man makes a profit of 8% by selling a commodity at Rs 540. Find the cost price of the commodity.

To find :

Cost price of the commodity

Solution :

• Selling price = Rs.540
• Profit = 8%
• Cost price = ???

According to selling price formula

$\implies\sf S.P=C.P\left(\frac{100+profit\%}{100}\right) \\ \\ \implies\sf 540=C.P\left(\frac{100+8}{100}\right) \\ \\ \implies\sf C.P=\frac{540×100}{108}=Rs.500$

Some Formulae :

★ $\sf S.P=C.P\left(\frac{100+profit\%}{100}\right)$

★ $\sf S.P=C.P\left(\frac{100-loss\%}{100}\right)$

★ Loss = C.P - S.P

★ Profit = S.P - C.P

★ Profit % = profit/C.P × 100

★ Loss % = loss/C.P × 100
