• A. Rs. 250 crores
• B. Rs. 300 crores
• C. Rs. 357 crores
• D. Rs. 420 crores

Answer 1

Answer: (D)

Rs. 420 crores

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.
$\therefore 1.25=\frac{250}{x}\Rightarrow x=\frac{250}{1.25}=200$ [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, $1.40=\frac{y}{300}\Rightarrow y=(300\times 1.40)=420$.
$\therefore$ Imports in the year 1999 = Rs. 420 crores.
