The correct answer is
$20\%$

Percentage Loss Calculation

Given Values

  • Cost Price (CP): ₹850
  • Selling Price (SP): ₹680

Loss Calculation

Loss occurs when Selling Price is less than Cost Price.

Loss = CP - SP

Loss = $850 - 680 = 170$

Percentage Loss Formula

Percentage Loss is calculated using the formula:

Percentage Loss = $\left( \frac{\text{Loss}}{\text{Cost Price}} \right) \times 100\%$

Calculate Percentage Loss

Substitute the values into the formula:

Percentage Loss = $\left( \frac{170}{850} \right) \times 100\%$

Simplify the fraction:

Percentage Loss = $\left( \frac{17}{85} \right) \times 100\%$

Since $\frac{17}{85} = \frac{1}{5}$:

Percentage Loss = $\frac{1}{5} \times 100\%$

Percentage Loss = $20\%$
