(i) The one with the lower rank in Maths between A and B had the least class rank
(ii) The one with the higher class rank between D and C had the least Math rank
(iii) The one with the lower class rank between B and C, had a better Math rank than exactly two other friends
(iv) The one with the lower Math rank between B and D, had the highest class rank

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)
