Direction: Read the following information and answer the question that follow.
In a study of five brands of pain relieving tablets P, Q, R, S and T, the brands were tested and ranked against each other as more or less effective per dose. The following results were obtained.
I. P was more effective than Q.
II. The effectiveness of R was less than that of S.
III. T was the least effective brand tested.
IV. Q and R were equally effective.
V. The effectiveness of S was greater than that of Q.
-
If R is more expensive per dose than P and T is less expensive per dose than R, which of the following must be true, according to the study, for a consumer, who wishes to buy a pain reliever with the greatest effectiveness for the amount spent per dose?
-
- P should be purchased instead of R
- P should be purchased instead of T
- T should be purchased instead of R
- Q should be purchased instead of R, if Q is of the same price as S
Correct Option: A
According to the question,
P > Q. S > R
T is least effective Q = R, S > Q
∴ S/P > Q = R > T
Now, it is given that P is less expensive than R and from the order, P is more effective than R. It means that P should be Purchased as it is more effective and less expensive than R
