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).
