Question

Directions : 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.

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?

• A. 23%
• B. 25%
• C. 35 %
• D. 16 %
• E. 19 %

Answer 1

The correct option is A

23%

Increase in wheat production:

Year 2003 $\Rightarrow \frac{2900\times 130}{100}$ = 3770 quintals

Year 2004 $\Rightarrow \frac{2900\times 140}{100}$ =4060 quintals

Year 2005 $\Rightarrow \frac{3000\times 145}{100}$ =4350 quintals

Year 2007 $\Rightarrow \frac{2900\times 140}{100}$=4060 quintals

Total earlier production of wheat in Madhya Pradesh

= 2400 + 3300 + 2900 + 2900 + 3000 + 2400 + 2900 = 19800 quintals

New wheat production =2400 + 3300 + 3770 + 4060 + 4350 + 2400 + 4060 = 24080 quintals Increase = 240340 – 19800 = 4540 quintals

Percentage increase = $\frac{4540}{19800}\times 100\approx 23\%$
