Question

12. A cloth dealer professes to sell poplin at cost price; but uses a metre having a length of 92 cm only and charges for the metre. Find his gain percent.​

Answer 1

Answer:

Step-by-step explanation:

let cost of 100 cm=X

cost of 90cm=90X/100

SP of 90cm =X

so profit=sp-cp=X-90X/100=10X/100

profit \: percent = \frac{profit \times 100}{cp} \\ = \frac{10x}{100} \times 100 \div \frac{90x}{100} \\ = \frac{10x}{100} \times 100 \times \frac{100}{90x} \\ = \frac{100}{9} = 11.11\%
