Explanation
1. Extract Initial Data from Pie Charts:
-
Total Sale Price of Car: Rs.100,000.
-
Margin (Profit): 10% of Sale Price =Rs.10,000.
-
Total Cost of Car: Sale Price−Margin=100,000−10,000=Rs.90,000.
-
Initial Transmission Cost: 20% of Sale Price =Rs.20,000.
-
Initial Engine Cost: 30% of Sale Price =Rs.30,000.
-
Other Costs (Chassis + Miscellaneous): (15%+25%) of Sale Price =40%=Rs.40,000.
2. Calculate New Costs After Increase:
-
New Transmission Cost:
Initial+10% increase=20,000+(0.10×20,000)=Rs.22,000
-
New Engine Cost:
Initial+20% increase=30,000+(0.20×30,000)=Rs.36,000
3. Calculate New Total Cost:
The total cost is the sum of the new component costs and the unchanged remaining costs.
New Total Cost=New Transmission+New Engine+Other Costs
New Total Cost=22,000+36,000+40,000=Rs.98,000
4. Calculate New Percentage Contribution of Transmission:
Percentage=(New Total CostNew Transmission Cost)×100
Percentage=(98,00022,000)×100≈22.448%
Conclusion:
The percentage contribution of transmission cost to the total cost is approximately 22.44%.
Correct Option: (b) 22.44%
