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) a) From the table, it is clear that total number of students enrolled in MBA (HR) = 756 + 306 = 1062

2) c) Number of girls enrolled in MBA (Finance) = 1098

=> Required Percentage = 1098/7200 × 100% = 15.25% = 15%

3) e) Number of girls enrolled in MBA (Marketing) = 522

4) d) Number of boys enrolled in MBA (Operations) = 1080

Number of girls enrolled in MBA (IT) = 480

=> Required Percentage = 1080/480 × 100% = 225%

5) b) Total number of boys enrolled in MBA (Entrepreneur) = 432
