The following table shows the production of food grains in a country over the five years.
| Year | Production (in ten lakh tonnes) | |||
| Wheat | Rice | Maize | Other grains | |
| 2016-17 | 650 | 250 | 200 | 450 |
| 2017-18 | 800 | 440 | 240 | 400 |
| 2018-19 | 680 | 390 | 220 | 500 |
| 2019-20 | 700 | 400 | 260 | 480 |
| 2020-21 | 640 | 440 | 300 | 520 |
The difference between the average production (in ten lakh tones ) of wheat and maize over the year is :
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 450
The average production (in ten lakh tones) of wheat = (650 + 800 + 680 + 700 + 640)/5 = 3470/5 = 694
The average production (in ten lakh tones) of maize = (200 + 240 + 220 + 260 + 300)/5 = 1220/5 = 244
The difference in production (in ten lakh tones) = 694 - 244 = 450
Therefore, the difference between the average production (in ten lakh tones ) of wheat and maize over the year is 450.
