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

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%
