If the production of wheat by Madhya Pradesh in the years 2003, 2004, 2005 and 2007 increase by 30%, 40%, 45% and 40% respectively, what will be the overall percentage increase in the production of wheat in the state in the given years ?

Increase in wheat production in Madhya Pradesh in the year :

2003 = $$\frac{130}{100}$$ * 2900 = 3510

2004 = $$\frac{140}{100}$$ * 2900 = 4060

2005 = $$\frac{145}{100}$$ * 3000 = 4350

2007 = $$\frac{140}{100}$$ * 2900 = 4060

=> Total new production = 2400 + 3300 + 3510 + 4060 + 4350 +2400 + 4060 = 24080

Total earlier production = 2400 + 3300 + 2900 + 2900 + 3000 + 2400 + 2900 = 19700

=> Increase = 24080 - 19700 = 4380

$$\therefore$$ % increase = $$\frac{4380}{19700}$$ * 100 = 22%
