Company B’s sale in 2010 = 85000

In 2011 = 75000

Company D’s sale in 2010 = 95000

In 2011 = 105000

Total sale of Company B = 85000 + 75000 = 160000

Total sale of Company D = 95000 + 105000 = 200000

Therefore, ratio = $\frac{160000}{200000} = \frac{4}{5}$ = 4:5

2. The bar graph below provides the information about the sales of computers (in thousand number) from six different company during 2010 and 2011. Study the graph properly and answer all the given questions.

Company F’s sale in 2010 = 80000

In 2011 = 90000

Company C’s sale in 2010 = 105000

In 2011 = 120000

Total sale of company F = 80000 + 90000 = 170000

Total sale of company C = 105000 + 120000 = 225000

Percentage = $\frac{170000}{225000} \times 100$ = 75.5%

Average of all the six companies in 2010 = $\frac{90 + 85 + 105 + 95 + 85 + 80}{6}$

=$\frac{540}{6} = 90$

Average of all the six companies in 2011 = $\frac{115 + 75 + 120 + 105 + 105 + 90}{6}$

= $\frac{610}{6} = 101.66$

Percentage = $\frac{90}{101.66} \times 100$ = 88.5%

5. The bar graph below provides the information about the export of a country (in million $) from the year 2001 to 2009. Study the graph properly and answer all the given questions. Find the ratio of the years, in which the export was above the average to those in which the export was below the average. 3:5 3:5 54.61% 5:3 5:3 28.95% 6:7 6:7 9.21% 9:10 9:10 7.24% The average of the export is: $\frac{3052 + 4165 + 2950 + 3722 + 3500 + 4780 + 5460 + 3500}{8} = 3891.12$ Those years in which the export was above 3891.12 were: 2002-03, 2006-07, and 2007-08. Therefore, for 3 years Those years in which the export was below 3891.12 were: 2001-02, 2003-04, 2004-05, 2005-06, and 2008-09. Therefore, for 5 years. Thus the ratio is 3:5 6. The bar graph below provides the information about the export of a country (in million$) from the year 2001 to 2009. Study the graph properly and answer all the given questions.

The ratio = $\frac{5460}{3722} = 1.46$

Therefore, the export of 2007-08 was 1.46 times the export in 2004-05.

7. The bar graph below provides the information about the export of a country (in million $) from the year 2001 to 2009. Study the graph properly and answer all the given questions. Find the year in which, the percent upsurge of export over the preceding year, was the lowest? 2002-03 2002-03 22% 2007-08 2007-08 51.33% 2004-05 2004-05 16% 2006-07 2006-07 10.67% The upsurge in export was in the year: 2002-03, 2004-05, 2006-07, and 2007-08. The increase in export compared to previous year: For 2002-03 = $\frac{4165-3052}{3052} \times 100$ = 36.46% For 2004-05 = $\frac{3722-2950}{2950} \times 100$ = 26.16% For 2006-07 = $\frac{4850-3500}{3500} \times 100$ = 38.57% For 2007-08 = $\frac{5460-4780}{4780} \times 100$ = 14.22% According to the above calculations it is clear that the percent upsurge of export over the preceding year was lowest in the year 2007-08. 8.

For 1988 = $\frac{55-50}{50} \times 100$ = 10%

For 1989 = $\frac{65-55}{55} \times 100$ = 18.18%

Therefore, the minimum increase/fall was in the year 1986.
