Given:
Graph which shows the ratio of the amount of imports by a company to the amount of exports from that company over the period from 2002 to 2009.
Formula used:
Percentage increase/decrease in a quantity is found by:
= OriginalChange×100
Calculation:
Ratio of amount of imports to exports by the company in 2002 = 0.5
Ratio of amount of imports to exports by the company in 2003 = 0.75
Ratio of amount of imports to exports by the company in 2004 = 0.45
Ratio of amount of imports to exports by the company in 2005 = 0.95
Ratio of amount of imports to exports by the company in 2006 = 0.85
Ratio of amount of imports to exports by the company in 2007 = 1.05
Ratio of amount of imports to exports by the company in 2008 = 0.65
Ratio of amount of imports to exports by the company in 2009 = 1.1
Percentage increase/decrease in amount of imports to exports of the company in 2003 to preceding year is:
= OriginalChange×100
= Ratio in 2002Ratio in 2003−Ratio in 2002×100
= 0.50.75−0.5×100
= 0.50.25×100
= 21×100
= 50% increase.
Percentage increase/decrease in amount of imports to exports of the company in 2004 to preceding year is:
= OriginalChange×100
= Ratio in 2003Ratio in 2004−Ratio in 2003×100
= 0.750.45−0.75×100
= 0.75−0.3×100
= -3000 / 75
= 40% decrease.
Percentage increase/decrease in amount of imports to exports of the company in 2005 to preceding year is:
= OriginalChange×100
= Ratio in 2004Ratio in 2005−Ratio in 2004×100
= 0.450.95−0.45×100
= 0.450.5×100
= 5000 / 45
= 111111% increase.
Percentage increase/decrease in amount of imports to exports of the company in 2006 to preceding year is:
= OriginalChange×100
= Ratio in 2005Ratio in 2006−Ratio in 2005×100
= 0.950.85−0.95×100
= -1000 / 95
= 101910% decrease.
Percentage increase/decrease in amount of imports to exports of the company in 2007 to preceding year is:
= OriginalChange×100
= Ratio in 2006Ratio in 2007−Ratio in 2006×100
= 0.851.05−0.85×100
= 2000 / 85
= 20176% increase.
Percentage increase/decrease in amount of imports to exports of the company in 2008 to preceding year is:
= OriginalChange×100
= Ratio in 2007Ratio in 2008−Ratio in 2007×100
= 1.050.65−1.05×100
= -4000 / 105
= -800 / 21
= 302117% decrease.
Percentage increase/decrease in amount of imports to exports of the company in 2009 to preceding year is:
= OriginalChange×100
= Ratio in 2008Ratio in 2009−Ratio in 2008×100
= 0.651.1−0.65×100
= 4500 / 65
= 900 / 13
= 601312% increase.
∴ 2005 has the highest percentage increase/decrease in the ratio of imports to exports as compared to the preceding year.
