Line Graph Question for Data Interpretation of Quantitative Aptitude 1

If the imports in 1998 was Rs. 250 crores and the total exports in years 1998 and 1999 together was Rs 500 crores, then the imports in 1999 was :

320 Crore
420 Crore
520 Crore
620 Crore

Answer: Option B

Explanation:

The Ratio of imports to exports for the years 1998 and 1999 are 1.25 and 1.40 respectively.
Let the exports in the year 1998 = Rs. x crores
Then,the exports in the year 1999 = (500-x) crores

=> 1.25 = 250/x [because 1.25 is 1998 ratio]

=> x = 250/1.25 = 200 crore

Thus the exports in the year 1999 were 500 - 200
= 300 crore

Let the imports in the year 1999 = Rs y crore
Then 1.40 = y/300
=> y = 1.40*300 = 420 crore
