What is the ratio of diesel cars manufactured by companies A and C together to the total cars manufactured by company F?

Accepted Answer

**Solution:**
**Step 1:** Find total cars manufactured.
Company F = 12.5% of total cars = 300
Total cars = 300 / 0.125 = 2400
**Step 2:** Find total petrol cars.
Company F petrol = 14% of total petrol cars = 210
Total petrol cars = 210 / 0.14 = 1500
**Step 3:** Find total and petrol cars for companies A and C.
Company A total = 17.5% × 2400 = 420
Company C total = 20% × 2400 = 480
Company A petrol = 8% × 1500 = 120
Company C petrol = 16% × 1500 = 240
**Step 4:** Find diesel cars for companies A and C.
Company A diesel = 420 - 120 = 300
Company C diesel = 480 - 240 = 240
Total diesel cars of A and C = 300 + 240 = 540
**Step 5:** Find the ratio.
Ratio = Diesel cars of A and C : Total cars of F = 540 : 300 = 9 : 5
**The correct answer is 9 : 5**
