In the following table, the production of various crops(in tonnes) is given from 2015 to 2019. Study the table and answer the questions that follow.
| Year | Rice | Wheat | Sugarcane | Barley | Maize |
| 2015 | 415 | 2500 | 1000 | 975 | 490 |
| 2016 | 520 | 4218 | 1120 | 825 | 520 |
| 2017 | 585 | 3482 | 1250 | 700 | 610 |
| 2018 | 625 | 4500 | 1325 | 625 | 725 |
| 2019 | 600 | 3300 | 1450 | 775 | 840 |
The difference (in tonnes) between the average production of barley and average production of rice is :
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 231
Explanation:
Total production of barley = 975 + 825 + 700 + 625 + 775 = 3900
Average = sum of the terms/total number of terms
Average production of barley = 3900/5 = 780
Total production of rice = 415 + 520 + 585 + 625 + 600 = 2745
Average production of rice = 2745/5 = 549
The difference (in tonnes) between the average production of barley and average
production of rice = 780 - 549 = 231
