### Question

You have to decide whether the data provided in the statements are sufficient to answer the question. Read the statements and give your answer.

P, Q, R are negative and T is a number. Is it negative?

1. T = P − Q.
2. T x R = P.
A

if statement I alone is sufficient but statement II alone is not sufficient.

B

if statement II alone is sufficient but statement I alone is not sufficient.

C

if both statements I and II together are sufficient but neither of statements alone is sufficient.

D

if each statement alone is sufficient.

Soln.
Ans: b

From the statement I, it can be negative as well as positive. Hence, statement I alone is not sufficient to answer the question. From statement II, it is clear that since P and R are negative hence t will be positive.
