View Hint View Answer Discuss in Forum
Total number of units manufactured = Units manufactured in 2004 + Units manufactured in 2005 + Units manufactured in 2006 + Units manufactured in 2007 + Units manufactured in 2008
Total number of units sold = Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008
Correct Option: C
Total number of units manufactured = Units manufactured in 2004 + Units manufactured in 2005 + Units manufactured in 2006 + Units manufactured in 2007 + Units manufactured in 2008
Total number of units manufactured = 4.5 + 5 + 5.5 + 5 + 7 = 27 crores
Total number of units sold = Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008
Total number of units sold = 3.5 + 4 + 5 + 3 + 6.5 = 22 crores
Hence, their difference = 27 crores  22 crores = 5 crores
 What is the respective ratio of the number of units manufactured in the year 2004 to the number of units manufactured in the year 2008?

View Hint View Answer Discuss in Forum
Required ratio = number of units manufactured in the year 2004 / number of units manufactured in the year 2008
Correct Option: D
Required ratio = number of units manufactured in the year 2004 / number of units manufactured in the year 2008
Required ratio = 4.5 : 7 = 45 : 70 = 9 : 14
 What is the average number of units sold over the years?

Average number of units sold = ( Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008 ) / 5
Correct Option: B
Average number of units sold = ( Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008 ) / 5
Average number of units sold = (3.5 + 4 + 5 + 3 + 6.5)/5 = 22/5 = 4.4 crores
 What is the approximate percent increase in the number of units sold in the year 2008 from the previous year?

View Hint View Answer Discuss in Forum
Required percentage of increase = (number of units sold in the year 2008  number of units sold in the year 2007) x 100 / number of units sold in the year 2007
Correct Option: D
Required percentage of increase = (number of units sold in the year 2008  number of units sold in the year 2007) x 100 / number of units sold in the year 2007
Required percentage of increase = (6.5  3) x 100/3 = 3.5 x 100/3 = 117%
 What is respective ratio of the difference between the number of units manufactured and sold in the year 2006 to the difference between the number of units manufactured and sold in the year 2007?

View Hint View Answer Discuss in Forum
Required ratio = (number of units manufactured in the year 2006  number of units sold in the year 2006)/ (number of units manufactured in the year 2007  number of units sold in the year 2007)
Correct Option: B
Required ratio = (number of units manufactured in the year 2006  number of units sold in the year 2006)/ (number of units manufactured in the year 2007  number of units sold in the year 2007)
Required ratio = (5.5  5) / (5  3) = 0.5 / 2 = 1 / 4 = 1 : 4
