SOLUTIONS
Let’s try to find out the information from given data and formulate a table based on that.
Number of student in the college = 7200
Number of boys = 7/12 × 7200 = 4200
Number of girls = 5/12 × 7200 = 3000
Number of students in MBA (Marketing) = 22% of 7200 = 1584
Number of girls in MBA (IT) = 16% of 3000 = 480
Number of boys in MBA (HR) = 18% of 4200 = 756
Number of girls in MBA (Entrepreneur) = 30% of 480 = 144
Number of boys in MBA (Finance) = 15% of 4200 = 630
Number of boys in MBA (IT) = 50% of 480 = 240
Number of girls in MBA (Operations) = 15% of 3000 = 450
Number of boys in MBA (Entrepreneur) = 3/1 × 144 = 432
Number of students in MBA (Finance) = 24% of 7200 = 1728
=> Therefore, Number of girls in MBA (Finance) = 1728 – 630 = 1098
Number of boys in MBA (Operations) = 12/5 × 450 = 1080
Number of boys in MBA (Marketing) = Remaining number of boys
= 4200 – (756+630+240+432+1080)
= 4200 – 3138 =1062
=> Therefore, Number of girls in MBA (Marketing) = 1584 – 1062 = 522
Number of girls in MBA (HR) = Remaining number of girls = 3000 – (480 + 144 + 450 + 1098 +
522)
= 3000 -2694 = 306
TABULAR FORM:
SUBJECTS NUMBER OF BOYS NUMBER OF GIRLS
MBA(IT) 240 480
MBA(HR) 756 306
MBA(ENTREPRENEUR) 432 144
MBA(FINANCE) 630 1098
MBA(OPERATIONS) 1080 450
MBA(MARKETING) 1062 522
Total 4200 3000
1) From the table, it is clear that total number of students enrolled in MBA (HR) = 756 + 306 = 1062
2) Number of girls enrolled in MBA (Finance) = 1098
=> Required Percentage = 1098/7200 × 100% = 15.25% = 15%
3) Number of girls enrolled in MBA (Marketing) = 522
4) Number of boys enrolled in MBA (Operations) = 1080
Number of girls enrolled in MBA (IT) = 480
=> Required Percentage = 1080/480 × 100% = 225%
5) Total number of boys enrolled in MBA (Entrepreneur) = 432
