The following line graph gives the ratio of the amounts of imports by a company to the amount of exports from that company over the period from 1995 to 2001.
Ratio of Value of Imports to Exports by a Company Over the Years.
If the imports in 1998 was Rs. 250 crores and the total exports in the years 1998 and 1999 together was Rs. 500 crores, then the imports in 1999 was ?
Rs. 250 crores
Rs. 300 crores
Rs. 357 crores
Rs. 420 crores
Correct answer is D
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 = Rs. (500 - x) crores.
Therefore 1.25 = 250/x => x = 250/1.25 = 200 [Using ratio for 1998]
Thus, the exports in the year 1999 = Rs. (500 - 200) crores = Rs. 300 crores.
Let the imports in the year 1999 = Rs. y crores.
Then, 1.40 = y/300 => y = (300 x 1.40) = 420
Therefore Imports in the year 1999 = Rs. 420 crores.
