Data Interpretation MCQ Questions and Answers - Line Chart

Clearly, Export > Import only when $$\frac{\text{Import}}{\text{Export}}$$   < 1.
From the graph it is clear that the above ratio is less than 1 in the years 2005, 2006, 2007 and 2010.
Thus (Imports : Exports) < 1 in 4 years

From graph, we find that the ratio of value of import to the value of export in 2006 is 0.85
Let the value of export in 2006 be Rs. $$x$$ crores.
Then,
$$\eqalign{ & \frac{272}{x} = 0.85 \cr & \Rightarrow x = \frac{272}{0.85} \cr & \Rightarrow x = \frac{272\times100}{85} \cr & \Rightarrow x = 320 \cr} $$
Hence, the value of exports in 2006 was Rs. 320 crores

Let the value of export in 2008 be Rs. $$x$$ crores
Then, the value of export in 2009 = Rs. (500 - $$x$$) crores
$$\eqalign{ & \frac{250}{x} = 1.25 \cr & \Rightarrow x = \frac{250}{1.25} \cr & \Rightarrow x = \frac{250\times100}{125} \cr & \Rightarrow x = 200 \cr} $$
∴ Export in 2008 = Rs. 200 crores
Export in 2009
  = Rs. (500 - 200) crores
  = Rs. 300 crores
Let the value of import in 2009 be Rs. $$y$$ crores
Then,
$$\eqalign{ & \frac{y}{300} = 1.40 \cr & \Rightarrow y = 1.40\times300 \cr & \Rightarrow y = \frac{140}{100}\times300 \cr & \Rightarrow y = 420 \cr} $$
Hence, the value of import in 2009 was Rs. 420 crores

The imports are minimum proportionate to exports means (value of import) : (value of export) should have minimum value.
Clearly, this ratio has a minimum value of 0.35 in 2007

The graph gives only the ratio of value of imports and that of exports.
In order to find the percentage increase in imports from 2007 to 2008, we require the value of import or that of export during these years.
So, we cannot find the percentage increase in imports.
Hence, the data is inadequate to answer the question.
