The table shows the production of different types of bikes (in thousands).
| Years | 2015 | 2016 | 2017 | 2018 |
| Bikes | ||||
| A | 157 | 194 | 271 | 290 |
| B | 138 | 225 | 146 | 206 |
| C | 255 | 227 | 213 | 239 |
| D | 196 | 304 | 162 | 224 |
The number of years, in which the production of bikes of type C is less than the average production of type A bikes over the years is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2%.
According to the given table,
Average number of bikes of type A = (157 + 194 + 271 + 290)/4
⇒ 912/4 = 228
Number of years in which production of type C bikes is less than 228 are 2016 and 2017.
Hence the required answer is 2.
