Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2016, 2018.
| Year | Production (P) | 90% of Production (P×0.9) | Sale (S) | Is S>90% of P? |
| 2015 | 1250 | 1250 × 0.9 = 1125 | 1000 | No (1000 < 1125) |
| 2016 | 1400 | 1400 × 0.9 = 1260 | 1290 | Yes (1290 > 1260) |
| 2017 | 1450 | 1450 × 0.9 = 1305 | 1100 | No (1100 < 1305) |
| 2018 | 1500 | 1500 × 0.9 = 1350 | 1450 | Yes (1450 > 1350) |
| 2019 | 1600 | 1600 × 0.9 = 1440 | 1390 | No (1390 < 1440) |
