S1. Ans.(d)
Sol. Total number of students studying B.Sc. in all the colleges together
= 350 + 325 + 300 + 375 + 425 = 1775
S2. Ans.(c)
Sol. 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
S3. Ans.(a)
Sol. 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
