According to given bar graph , we have
Number of families in daily income interval 800-900 = 40
Number of families in daily income interval 900-1000 = 15
Required number of families = Number of families in daily income interval 800-900 + Number of families in daily income interval 900-1000Correct Option: B
According to given bar graph , we have
Number of families in daily income interval 800-900 = 40
Number of families in daily income interval 900-1000 = 15
Required number of families = Number of families in daily income interval 800-900 + Number of families in daily income interval 900-1000
Required number of families = 40 + 15 = 55

As per the given above bar graph , we have
Number of families who have daily income interval 0-100 = 15
Number of families who have daily income interval 100-200 = 10
Number of families who have daily income interval 200-300 = 40
Number of families who have daily income interval 300-400 = 5
Number of families who have daily income interval 400-500 = 20
Number of families who have daily income interval 500-600 = 30
Number of families who have daily income interval 600-700 = 15
Number of families who have daily income 700-800 = 10
Number of families who have daily income interval 800-900 = 40
Number of families who have daily income interval 900-1000 = 15Correct Option: C

From the given above bar graph , we can see
Total number of men per interval = 100 + 220 + 300 + 200 + 250 = 1070
Number of men = 5Required average = Total number of men per interval Number of men
Correct Option: C
From the given above bar graph , we can see
Total number of men per interval = 100 + 220 + 300 + 200 + 250 = 1070
Number of men = 5Required average = Total number of men per interval Number of men Required average = 1070 = 214 5

On the basis of given graph in question ,
The production in 2007-08 = 1200
The production in 2003-04 = 600
Increase in production = 1200 - 600 = 600Required percentage increase = Increase in production × 100 The production in 2003-04
Correct Option: D
On the basis of given graph in question ,
The production in 2007-08 = 1200
The production in 2003-04 = 600
Increase in production = 1200 - 600 = 600Required percentage increase = Increase in production × 100 The production in 2003-04 Required percentage increase = 600 × 100 = 100% 600

According to given bar graph , we have
The production in 2006-07 = 1000
The production in 2007-08 = 1200
Increase in production = 1200 - 1000 = 200Percentage increase in 2007-08 = 200 × ́100 = 20% (lowest) 1000
The production in 2006-07 = 1000
The production in 2005-06 = 800
Increase in production = 1000 - 800 = 200
Correct Option: A
According to given bar graph , we have
The production in 2006-07 = 1000
The production in 2007-08 = 1200
Increase in production = 1200 - 1000 = 200Percentage increase in 2007-08 = 200 × ́100 = 20% (lowest) 1000
The production in 2006-07 = 1000
The production in 2005-06 = 800
Increase in production = 1000 - 800 = 200Percentage increase in 2006-07 = 200 × ́100 = 25% 800
