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.

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
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
 In which year or years, the difference between the number of working and nonworking women the lowest?

View Hint View Answer Discuss in Forum
From the given bar diagram , we see
The number of nonworking 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 nonworking 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 nonworking 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 nonworking 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 .
