From the given bar diagram , we see
Total amount invested in raw materials in given years = 120 + 225 + 375 + 330 + 252 + 420 = 1995
Number of given years = 6Average of total investment = Total amount invested in raw materials in given years Number of given years Average of total investment = 1995 = $ 332.5 lakhs 6
Total value of sales of finished goods in given years = 200 + 300 + 500 + 400 + 600 + 460 = 2460
Number of given years = 6Average value of sales = Total value of sales of finished goods in given years Number of given years
Correct Option: D
From the given bar diagram , we see
Total amount invested in raw materials in given years = 120 + 225 + 375 + 330 + 252 + 420 = 1995
Number of given years = 6Average of total investment = Total amount invested in raw materials in given years Number of given years Average of total investment = 1995 = $ 332.5 lakhs 6
Total value of sales of finished goods in given years = 200 + 300 + 500 + 400 + 600 + 460 = 2460
Number of given years = 6Average value of sales = Total value of sales of finished goods in given years Number of given years Average value of sales = 2460 = $ 410 lakhs 6
Difference = Average value of sales - Average of total investment
Difference = 410 – 332.5 = 77.5 lakh

According to given bar graph , we have
The amount invested in raw materials in 1996 = $ 225 lakhs
The amount invested in raw materials in 1995 = $ 120 lakhs
Increase = 225 - 120 = $ 105 lakhs
In Year 1996 ⇒Percentage increase = Increase The amount invested in raw materials in 1995 Percentage increase = 105 × 100 ≈ 87.5% 120
The amount invested in raw materials in 1996 = $ 225 lakhs
The amount invested in raw materials in 1997 = $ 375 lakhs
Increase = 375 - 225 = $ 150 lakhs
Correct Option: A
According to given bar graph , we have
The amount invested in raw materials in 1996 = $ 225 lakhs
The amount invested in raw materials in 1995 = $ 120 lakhs
Increase = 225 - 120 = $ 105 lakhs
In Year 1996 ⇒Percentage increase = Increase The amount invested in raw materials in 1995 Percentage increase = 105 × 100 ≈ 87.5% 120
The amount invested in raw materials in 1996 = $ 225 lakhs
The amount invested in raw materials in 1997 = $ 375 lakhs
Increase = 375 - 225 = $ 150 lakhs
In Year 1997 ⇒Percentage increase = 150 × 100 ≈ 67% 225
Therefore , required answer is 1996 year.

Number of give years = 5Required average = Total Kharif production of the given years Number of give years
Correct Option: A
On the basis of given graph in question ,
Total Kharif production of the given years = 5 + 4 + 4 + 3 + 4 = 20
Number of give years = 5Required average = Total Kharif production of the given years Number of give years Required average = 5 + 4 + 4 + 3 + 4 million tonnes = 4 million tonnes 5
Direction: Study the following multiple bar graph carefully and answer the questions

-
View Hint View Answer Discuss in Forum
From the given bar diagram , we see
The number of non-working women in the year 2006 = 60 millions
The number of working women in the year 2006 = 50 millions
Difference in 2006 = 60 - 50 = 10 millions
The number of non-working women in the year 2007 = 50 millions
The number of working women in the year 2007 = 60 millions
Difference in 2007 = 60 - 50 = 10 millionsCorrect Option: A
From the given bar diagram , we see
The number of non-working women in the year 2006 = 60 millions
The number of working women in the year 2006 = 50 millions
Difference in 2006 = 60 - 50 = 10 millions
The number of non-working women in the year 2007 = 50 millions
The number of working women in the year 2007 = 60 millions
Difference in 2007 = 60 - 50 = 10 millions
Hence , required years are 2006 and 2007 in which difference between them is lowest .

On the basis of given graph in question ,
The number of non-working women in the year 2010 = 35 millions
The number of working women in the year 2010 = 85 millions
Required difference = The number of working women in the year 2010 - The number of non-working women in the year 2010Correct Option: D
On the basis of given graph in question ,
The number of non-working women in the year 2010 = 35 millions
The number of working women in the year 2010 = 85 millions
Required difference = The number of working women in the year 2010 - The number of non-working women in the year 2010
Difference in 2010 = 85 – 35 = 50 million
