Answer & Explanation

**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**

**4.**
