1. Total number of students studying B.Sc. in all the colleges together 
    = 350 + 325 + 300 + 375 + 425 = 1775.

2. Total number of students studying B.Sc. in the colleges C and E together = 300 + 425 = 725
   Total number of students studying B. A. in the colleges A and B together = 275 + 300 = 575
   Required ratio = 725 : 575 = 29 : 23

3. Total number of students studying B.Sc. in all the colleges together
   = 350 + 325 + 300 + 375 + 425 = 1775

   Total number of students studying B.A. in all the colleges
   together = 275 + 300 + 325 + 450 + 325 = 1675

   Total number of students studying B.com in all the colleges
   together = 425 + 475 + 325 + 425 + 225 = 1875

   Required ratio = B.Sc. : B.A. : B.Com.
   = 1775 : 1675 : 1875 = 71 : 67 : 75

4. No. of students studying B.Com in college C = 35
   No. of students studying B.Com in all colleges together
   = (325*100)/1875 = 17 (approx.)

5. No. of students studying B.A. in college B = 300
   Total no. of students studying B.A., B.Sc and B.Com in college B
   = 300+325+475 = 1100

   Required Percentage = 300*100/1100 = 27.27%

6. Required percentage = 31/15×100 = 206.67 » 207 (approx.)

7. Total number of males in all the organizations = 1890 + 4235 + 6510 + 2100 + 1225 = 15960

8. Total number of males in organization A and C
   = 1890 + 6510 = 8400.

9. No. of females in organisation B = 35000*22*9/(100*20) = 3465
   No. of females in organisation E = 35000*14*3/(100*4) = 3675

   Required difference is = 3675 - 3465 = 210.


10. No. of females in organisation D = 35000*(15/100)*(60/100) = 3150.
