Directions to Solve
Answer the questions based on the given line graph.
Ratio of Exports to Imports (in terms of money in Rs. crores) of Two Companies Over the Years.
Question 1.
In how many of the given years were the exports more than the imports for Company A?
Question 2.In which year(s) was the difference between impors and exports of Company B the maximum?
Answer: Option D Explanation: We shall try to find the difference between the imports and exports of Company B for various years one by one: For 1995: We have \frac{E}{I} = 0.75 where E = amount of exports, I = amount of imports in 1995.
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 is known. Since the imports or exports for various years are not know, the differences between and exports for various years cannot be determined. |
E = 0.75I
I – E = I – 0.75 x I = 0.25I.Question 3.In 1995, the export of Company A was double that of Company B. If the imports of Company A during the year was Rs. 180 crores, what was the approximate amount of imports pf Company B during that year?
Answer: Option B Explanation: In 1995 for Company A we have: \frac{E_{A}}{I_{A}} =1.75 [where EA = amount of exports, IA = amount of imports of Company a in 1995] In 1995 for Company B we have: \frac{E_{B}}{I_{B}} =0.75 |
[where EB = amount of exports, IB = amount of imports of Company B in 1995]
Also, we have EA = 2EB … (iii)
Substituting IA = Rs. 180 crores (given) in (i), we get:
EA = Rs. (180 x 1.75) crores = Rs. 315 crores.
Using EA = Rs. 315 crores in (iii), we get:
E_{B} = \frac{E_{A}}{2} = \frac{315}{2} crores
Substituting E_{B} = \frac{315}{2} crores in (ii) we get
I_{B} = \frac{E_{B}}{0.75} = Rs \frac{315}{2 \times 0.75} = 210 crores
i.e., amount of imports of Company B in 1995 = Rs. 210 crores.
