Explanation

Cost Price per cm: For Rs. 100, the merchant gets 100+5=105100 + 5 = 105 cm. CP per cm=100105=2021 Rs/cm\text{CP per cm} = \frac{100}{105} = \frac{20}{21}\text{ Rs/cm}

Selling Price per cm: Marked Price = Rs. 110 per meter. With 5%5\% discount, SP per meter charged to customer = 110×0.95=104.5110 \times 0.95 = 104.5 Rs. For 100 cm paid by customer, merchant actually gives 95 cm. SP per cm=104.595=1.1 Rs/cm\text{SP per cm} = \frac{104.5}{95} = 1.1\text{ Rs/cm}

Profit Percentage: Profit %=(SPCP−1)×100=(1.120/21−1)×100=(23.120−1)×100=15.5%\text{Profit \%} = \left(\frac{\text{SP}}{\text{CP}} - 1\right) \times 100 = \left(\frac{1.1}{20/21} - 1\right) \times 100 = \left(\frac{23.1}{20} - 1\right) \times 100 = 15.5\%
