Imports in 2012 = Rs. 600 crores
Let Exports in 2012 = Rs. $$y$$ crores
Ratio of imports and exports in 2012 = 1.4
=> $$\frac{600}{y} = 1.4$$
=> $$y = \frac{600}{1.4} = 428.57$$
Total exports In the years 2012 and 2013 together = Rs. 2400 crores
=> Exports in 2013 = Rs. (2400 - 428.57) crores = Rs. 1971.43 crores
Let imports in 2013 = Rs. $$x$$ crores
Ratio of imports and exports in 2013 = $$\frac{x}{1971.43} = 0.7$$
=> $$x = 1971.43 \times 0.7 = 1380.001 \approx 1380$$
$$\therefore$$ Imports in 2013 was Rs. 1380 crores
=> Ans - (D)
