In the following multiple graphs production of wheat (in quintals) by three states – Bihar, Madhya Pradesh and Punjab-have been given. Study the following graphs carefully to answer the questions.
By what per cent is the total production of wheat by three states in the years 2002,2003 and 2004 more or less than that in the years 2005, 2006 and 2007 ?
Wheat produced by the three states in :
2002 = 3300 + 2900 + 2700 = 8900
2003 = 2800 + 2700 + 3700 = 9200
2004 = 2900 + 3100 + 3800 = 9800
=> Total production in these years = 8900 + 9200 + 9800 = 27900
2005 = 2100 + 3000 + 3500 = 8600
2006 = 2400 + 2900 + 3800 = 9100
2007 = 2900 + 3400 + 3600 = 9900
=> Total production in these years = 8600 + 9100 + 9900 = 27600
$$\therefore$$ Required % = $$\frac{27900 - 27600}{27600} * 100$$ = 1.09%
