As per the given bar graph , we have
Number of Science students in 2007-08 = 500
Number of Science students in 2006-07 = 450
Increase = 500 - 450 = 50Percentage increase in Science students = Increase × 100 Number of Science students in 2006-07 Percentage increase in Science students = 50 × 100 450
Correct Option: B
As per the given bar graph , we have
Number of Science students in 2007-08 = 500
Number of Science students in 2006-07 = 450
Increase = 500 - 450 = 50Percentage increase in Science students = Increase × 100 Number of Science students in 2006-07 Percentage increase in Science students = 50 × 100 450 Percentage increase in Science students = 100 = 11.1% 9

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
