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.
