Direction: Refer to the following statements and answer the questions:
Seven student Priya, Ankit, Raman, Sunil, Tony, Deepak and Vicky take a series of tests. No two students get similar marks. Vicky always scores more than Priya. Priya always scores more than Ankit. Each time either Raman scores the highest and Tony gets the least, or alternatively Sunil scores the highest and Deepak or Ankit scores the least.

It Raman gets the highest, Vicky should be ranked not lower than

Vicky > Priya
Priya > Ankit
One of them is true- Raman is highest or Tony is least or Sunil got highest and Deepak got least.
Now or each and every question we have different case-
If Raman Sunil got the highest, then Tony will get least and be ranked 7th.
