2.5; From I - T > P > D and N Nothing is mentioned about Yusuf and Rajan. So, I alone is not sufficient. From II - T > R > Y Nothing is mentioned about Teena, Piyush and Dhruv. So, II alone is not sufficient. From I and II - T > P > D & N and T > R > Y Thus, it is clear that T is tallest among them, thus, both are necessary to answer.

3.1; From I - ri means is - thus, I alone is sufficient. From II - We can’t find what ‘ri’ means. Thus, II alone is not sufficient.

5.  1; From I - Let Rohit age be X, Mohit’s age = 3X

Now, 3x + x = 36, 4x = 36 = x = 9

So, I alone is sufficient. From II - Rohit age is twice the age of Rohan but nothing is given about Rohan's age. So, II alone is not sufficient.
