Eight boys Anil, Kamal, Ram, Sanjay, Aakash, Vivek, Rahul and Ramu are sitting around a circular table facing towards the centre (not necessarily in the same order). Vivek is third to the right of Kamal, Kamal is second to the right of Sanjay. Ram is second to the right of Anil. Anil is second to the right of Vivek. Rahul is third to the right of Aakash. Who is second fo the right of Kamal?

Ramu 

Answer: Ramu

In this question first place Kamal and Vivek, now place Sanjay second to the left of Kamal. Now place Anil to the second right of Vivek. And now place Ram to the second right of Anil.

Now only 3 places are left, place Aakash to the immediate right of Kamal and place Rahul accordingly. The only place left is of Ramu.
