Study the given graph and answer the following questions. 45% of the total production of barley in given 4 years is what per cent more than the average production (per year) of wheat, rice and barley in 2017?
53%
Calculation:
Total barley production in 4 years = 250 + 450 + 450 + 550 = 1700 lakh tonnes
45% of total barley production = 0.45 × 1700 = 765 lakh tonnes
Average production of wheat, rice, barley in 2017 = 550 + 500 + 450 = 1500 ÷ 3 = 500 lakh tonnes
Difference = 765 - 500 = 265 lakh tonnes
Difference % = \(265\over500\) × 100 = 53%
∴ The answer is 53%.
