In which years was the difference between imports and exports of Company B the maximum?
Cannot be determined
The difference between the imports and exports of Company B for various years are as follows:
For 1995:
We have EI= 0.75 (where E = amount of exports and I = amount of imports in 1995)
⇒E=0.75I∴I−E=I−0.75I=0.25I
Thus, the difference between the imports and exports of Company B in 1995 is dependent on the amount of imports of Company B in 1995.
Similarly, the difference for other years can be determined only if the amount of imports for these years are known. Since the imports or exports for various years are not known, the differences between imports and exports for various years cannot be determined.
