Question

Is Ravi north of Meera?

Statements

1. Ravi is east of Meera.
2. Ravi is north-east of Meera.

Answer

Statement 2 alone is sufficient.

Solution

1. Being east does not establish whether Ravi is north or south, so statement 1 is insufficient.
2. North-east explicitly places Ravi north of Meera.
3. Therefore statement 2 alone is sufficient.
