Directions(6-10): Following line graph shows the ratio of exports to imports of two
companies A and B over the period 2000 to 2006.


6. If the import of Company A in 2002 was 96.8 lakh, what was the export of Company A in that year?
   32.44 lakh
   31.15 lakh
   24.2 lakh
   20.8 lakh
   33.5 lakh
   Option C
   E(A)/I(A) = 0.25
   E = 0.25 × 96.8 = 24.2 lakh

    

7. If the import of Company A in year 2005 and export of Company B in year 2006 are 86 lakh and 51 lakh respectively, what is the sum of export of Company A in 2005 and import of Company B in 2006?
   201.5 lakh
   153.8 lakh
   185.5 lakh
   150.7 lakh
   202.5 lakh
   Option B
   E(A)/I(A) = 0.8
   EA = 0.8 × IA = 0.8 × 86 = 68.8 lakh
   E(B)/I(B) = 0.6 I(B) = E(B)/0.6 = 51/0.6 = 85 lakh
   Sum = 85 + 68.8 = 153.8 lakh

    

8. The ratio of export to import of Company B in year 2002 was what percentage of the ratio of export to import of Company A in year 2000?
   130.0%
   125.5%
   132.8%
   129.2%
   137.5%
   Option E
   In 2004:
   E(B)/I(A) = 0.55
   In 2002:
   E(B)/I(A) = 0.4
   Required % = 0.55/0.4*100 = 137.5%

    

9. If the export of Company A in year 2003 and that of B in year 2000 were 23.4 lakh and 72 lakh respectively, then the import of Company A in year 2003 is what percentage of the import of Company B in year 2000?
   81.25%
   95.22%
   80.32%
   78.23%
   75.25%
   Option A
   For A: E/I = 0.3
   I = E/0.3 = 23.4/0.3 = 78 lakh
   For B: E/I = 0.75
   I = E/0.75 = 72/0.75 = 96 lakh
   Required% = 78/96*100 = 81.25%

    

10. If in year 2003 the export of Company B is increased by 125% and its import is decreased by 60%, what will the new ratio of export to import of Company B in 2003?
    9:7
    11:13
    7:8
    9:4
    10:11
    Option D
    E/I = 0.4
    Let the new export be E1 and import be I1.
    Then, E1 = (E+ E*125)/100 = 225E/100
    I1 = (I – I*60)/100 = 40*I/100
    New Ratio = E1/I1 = 225E/100*100/40*I = 225/40 * E/I = 9:4
