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


A) 250 crores

B) 300 crores

C) 357 crores

D) 420 crores

E) None of these

Answer:

Option D

Explanation:

Let the value of export in 2008 be x crores.

Then, the value of export in 2009 = (500 - x) crores

$\frac{250}{x}$ = 1.25 

$x= \frac{250}{1.25}$ = 200

Export in 2008 = 200 crores.

Export in 2009 =  (500 - 200) crores = 300 crores.

Let the value of import in 2009 be y crores.

Then, $\frac{y}{300}$ = 1.40

$y = 1.40\times300$ = 420 

Hence, the value of import in 2009 was  420 crores.
