Understanding the ProblemThe shopkeeper sells a cricket bat for Rs 570 and incurs a loss of 5%. To calculate the cost price (CP) of the bat, we first need to understand the relationship between selling price (SP), cost price, and loss percentage.
Calculating Cost Price (CP)The formula to find the cost price when there is a loss is:
CP = SP / (1 - Loss Percentage)
Given:
- Selling Price (SP) = Rs 570
- Loss Percentage = 5% = 0.05
Substituting the values into the formula:
CP = 570 / (1 - 0.05) = 570 / 0.95 = Rs 600
Calculating Selling Price for a GainNow, to find the selling price at which the shopkeeper should sell the cricket bat to gain 5%, we use a similar formula:
SP = CP × (1 + Gain Percentage)
Where:
- Gain Percentage = 5% = 0.05
Substituting the cost price we calculated:
SP = 600 × (1 + 0.05) = 600 × 1.05 = Rs 630
ConclusionTo gain a profit of 5% on the cricket bat, the shopkeeper should sell it for:
Rs 630
This calculation ensures the shopkeeper achieves his desired profit margin while effectively managing his costs.
