The given bar graph shows the biscuit exports of India over a period of five years. Study the graph and answer the question that follow.

In which two years was the value per tonne equal?

From the bar graph,

Value per tonne of the exports in 2005 = $$\frac{150}{100}=1.5$$ crore/lakh tonne = 1.5 x 10$$^{-5}$$ crore/tonne

Value per tonne of the exports in 2006 = $$\frac{150}{75}=2$$ crore/lakh tonne = 2 x 10$$^{-5}$$ crore/tonne

Value per tonne of the exports in 2007 = $$\frac{330}{150}=2.2$$ crore/lakh tonne = 2.2 x 10$$^{-5}$$ crore/tonne

Value per tonne of the exports in 2008 = $$\frac{400}{160}=2.5$$ crore/lakh tonne = 2.5 x 10$$^{-5}$$ crore/tonne

Value per tonne of the exports in 2009 = $$\frac{500}{200}=2.5$$ crore/lakh tonne = 2.5 x 10$$^{-5}$$ crore/tonne

$$\therefore\ $$In 2008 and 2009, value per tonne is equal.

Hence, the correct answer is Option B
