According to given bar graph , we have
Number of students admitted in the year 2002 = 8 thousands
Total number of students passed out in the years 2003 and 2004 = 9 + 9 = 18 thousands
Number of given years = 2
Required ratio = Number of students admitted in the year 2002 : Average of the number of students passed out in the years 2003 and 2004Correct Option: B

As per the given bar graph , we have
During 2000 to 2003,
Total students admitted = (6 + 9 + 8 + 12) thousands = 35 thousands
Total students passed = (4 + 6 + 6 + 9) thousands = 25 thouseands
∴ Required ratio = Total students passed : Total students admittedCorrect Option: D
