If the imports in 2008 was Rs. 250 crores and the total exports in the years 2008 and 2009 together was Rs. 500 crores, then the imports in 2009 was-

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
