Directions (1-5): Following line graph shows the ratio of import and export of two companies Aand B over the years 2004-2009. Answer the questions based on this graph.
1. If the import of Company A is Rs 48 lakhs in year 2007 then what is its export in that year?
Ans: (1)
i/e = 1.2
e = i/1.2 = 48/1.2 = 40
2. What is the ratio of number of years in which Company A’s export is less than import and the number of years in which Company B’s import less than export?
For A, in years 2007 and 2009, import > export
For B, in all six years, import < export
Ratio = 2/6 = 1/3 = 1:3
3. If the export of Company A in 2006 and export of Company B in 2007 is 75 lakhs each, then the import of Company A in 2006 is what percent of the import of Company B in 2007?
For A, in 2006, i/e = 0.64
Income = 0.64 × 75 = 48
For B, in 2007, i/e = 0.8
i = 0.8 × 75 = 60
% = 48/60 × 100 = 80%
4. If the import of Company B is 60 lakhs in 2008, then what is the export of Company A in the same year?
Data is not sufficient.
5. What is the ratio of the ratio of import to export of Company B in year 2004 and the ratio of export to import of Company A in year 2007?
In 2004, iB / eB = 0.8 = 4/5
In 2007, iA / eA = 1.2 = 6/5
eA / iA = 5/6
Ratio between them = (4/5)/(5/6) = 24:25
Directions (6-10): Study the following diagrams carefully and answer the given questions.
Polio cases reported from various states during the given years.
Total Polio Cases in India
6. In which state the difference between polio cases in 2002 and 2003 is 11, and which had zero incidence in 2001?
MP A slight look is sufficient to answer this question.
7. What is the difference between the average number of polio cases of the five given states in 2002 and that in 2003?
Required difference
= ((37-3) + (39-28) + (121-13) + (21-10)+(24-3))/5
= 185/5 = 37
8. Approximately what per cent of polio cases was reported in Bihar in 2002 with respect to total cases reported in India that year?
Total P cases in Bihar (2002) = 121
Total P cases in India (2002) = 1600
Requiredd answer = 121/1600 × 100 = 7.5% (approx)
9. Polio cases in Haryana in 2003 and Bihar in 2001 together is what per cent of the polio cases in Delhi in 2002?
Reqd percentage = (3+27)/24 × 100 = 125%
10. Find the ratio between the total no. of cases in the five given states to that in the rest of country in 2001.
Total P cases in India (2001) = 268
Total P cases in the given states (2001) = 36
Hence, reqd. ratio = 36/(268 - 36) = 36/232 = 9 : 58.
- (1) 40 lakhs
- (2) 57.6 lakhs
- (3) 42 lakhs
- (4) 54 lakhs
- (5) None of these
Ans: (1)
i/e = 1.2
e = i/1.2 = 48/1.2 = 40
- (1) 4 : 1
- (2) 1 : 3
- (3) 5 : 6
- (4) 3 : 2
- (5) None of these
For A, in years 2007 and 2009, import > export
For B, in all six years, import < export
Ratio = 2/6 = 1/3 = 1:3
- (1) 75%
- (2) 80%
- (3) 100%
- (4) 120%
- (5) 150%
For A, in 2006, i/e = 0.64
Income = 0.64 × 75 = 48
For B, in 2007, i/e = 0.8
i = 0.8 × 75 = 60
% = 48/60 × 100 = 80%
- (1) 30 lakhs

5. What is the ratio of the ratio of import to export of Company B in year 2004 and the ratio of export to import of Company A in year 2007?
- (1) 2 : 3
- (2) 3 : 2
- (3) 5 : 6
- (4) 4 : 5
- (5) 24 : 25
In 2004, iB / eB = 0.8 = 4/5
In 2007, iA / eA = 1.2 = 6/5
eA / iA = 5/6
Ratio between them = (4/5)/(5/6) = 24:25
