How for is point P from Point Q? (All the point lie on a straight line.)
I. Point T is exactly midway between Point P and Q.
Point T is 5 km towards the west of Point R.
II. Point Q is 2 km towards the east of Point R.

1. if the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
2. if the data in Statements II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
3. if the data either in Statement I alone or in Statement II alone are sufficient to answer the question.
4. if the data in both the Statement I and II together are not sufficient to answer the question.
5. if the data in both the Statement I and II together are necessary to answer the question.

Using I:
T 5 R and T is midway between P and Q
Using II:
R 2 Q
Using both:
P 7 T 5 R 2 Q
