A question is given below followed by two statements numbered I and II each containing some information. Decide which of the statements are sufficient to answer the question?
Q. Rohan is in which direction with respect to Pankaj?
Statement I: Rohan is to the South of Tanya who is to the East of Dolly.
Statement II: Pankaj is to the East of Tanya.

Question:
Rohan is in which direction with respect to Pankaj?

Statement I:
Rohan is to the south of Tanya. Tanya is to the east of Dolly.
This gives no information about Pankaj.
So, statement I alone is not sufficient.

Statement II:
Pankaj is to the east of Tanya.
This gives no information about Rohan.
So, statement II alone is not sufficient.

Using both statements together:
Rohan is south of Tanya and Pankaj is east of Tanya.
So, Rohan is to the south-west of Pankaj.
