Answers & Solutions (1 – 5):

First let’s write down the conditions given for Class rank and Math rank separately.

We see A and B are present in both the columns. Thus, making assumptions based on them will yield the most result. Let’s first assume A has a lower Math rank than B.

From I, A has the least class rank. Thus, from IV, A has the highest Math rank. This contradicts our assumption. Thus, A definitely has a higher Math rank than B.

Thus, from I. B is 4th in Class rank. From V. B is the second in Math. Since A has higher Math rank than B, A will be the 1st in Math. Applying II, we get D is the 1st in the Class. Further using conditions III and IV, the following table can be formed.

1) Answer (A)
2) Answer (A)
3) Answer (D)
4) Answer (C)
5) Answer (A)
