💡 Analysis & Explanation
Cost Price Derivation ▼
For the first dryer sold at a 5% profit, the Cost Price (CP) is 63000 / 1.05 = 60,000. For the second dryer sold at a 30% loss, the CP is 63000 / 0.70 = 90,000.
Total Transaction Analysis ▼
The combined Total CP for both items is 60000 + 90000 = 1,50,000. The combined Total Selling Price (SP) is 63000 + 63000 = 1,26,000.
Loss Calculation ▼
The overall monetary loss is Total CP - Total SP = 150000 - 126000 = 24,000.
Percentage Evaluation ▼
The loss percentage is calculated as (Loss / Total CP) * 100, which is (24000 / 150000) * 100 = 16%.
Conclusion ▼
The net loss on the entire transaction is exactly 16%.
