Question

Determine : What is the ratio of diesel cars in State 4 to electric cars in State 3 ?

• A. 7:3
• B. 7:4
• C. 13:7
• D. 4:7
• E. 3:7

Hint:

In ratio-percentage DI problems, first find the actual total for each state (percentage $\times$ grand total), then apply the given ratio to find individual categories.

Answer 1

The Correct Option is A

Step 1: Concept Analysis:
This is a Data Interpretation question involving ratios and percentages.

Step 2: Solution Approach:
Total cars = 8000. State 4: $35% \times 8000 = 2800$ cars, ratio diesel:petrol:electric = 7:5:2, total parts = 14. Diesel in State 4 $= \frac{7}{14} \times 2800 = 1400$. State 3: $30% \times 8000 = 2400$ cars, ratio = 4:5:3, total parts = 12. Electric in State 3 $= \frac{3}{12} \times 2400 = 600$. Ratio $= 1400 : 600 = 7:3$.

Step 3: Conclusion:
The ratio of diesel cars in State 4 to electric cars in State 3 is 7:3.
