| Company → | A | B | C | D |
| Year ↓ | ||||
| 2013 | 45 | 63 | 65 | 67 |
| 2014 | 52 | 49 | 60 | 69 |
| 2015 | 61 | 60 | 66 | 67 |
| 2016 | 72 | 58 | 70 | 63 |
| 2017 | 52 | 53 | 63 | 75 |
| 2018 | 53 | 67 | 76 | 74 |
What is the ratio of the total number of cars sold by companies A, B and D in 2017 to the total number of cars sold by all four companies in 2018?
Show answer & explanation
Correct answer: C
Explanation
Ratio = 2 : 3
- 2017: A + B + D = 52 + 53 + 75 = 180
- 2018: A + B + C + D = 53 + 67 + 76 + 74 = 270
- 180 : 270 = 2 : 3
