Question : Direction: The following table shows the production of food grains (in million tonnes) in a state for the period 1999-2000 to 2003-2004. Read the table and answer the question.
| Production (in million tonnes) | ||||
| Year | Wheat | Rice | Barley | Other cereals |
| 1999-2000 | 680 | 270 | 250 | 450 |
| 2000-2001 | 800 | 420 | 440 | 300 |
| 2001-2002 | 680 | 350 | 320 | 460 |
| 2002-2003 | 720 | 400 | 380 | 500 |
| 2003-2004 | 820 | 560 | 410 | 690 |
The difference between the average production of rice and the average production of barley over the years is (in million tonnes).
Option 1: 50
Option 2: 60
Option 3: 80
Option 4: 40
Correct Answer: 40
Solution :
Total production of rice in given years = 270 + 420 + 350 + 400 + 560 = 2000
Total production of barley in given years = 250 + 440 + 320 + 380 + 410 = 1800
Number of years = 5
Required difference = $\frac{\text{Total production of rice – Total production or barley}}{\text{Number of years}}$
= $\frac{2000-1800}{5}$
= 40
Hence, the correct answer is 40 (million tonnes).
