Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question.
Who among P, Q, R, S and T is the lightest?
I. R is heavier than Q and T but lighter than S.
II. S is not the heaviest.

Options

A. 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
B. if the data in statement II alone are sufficient to answer the question, while the data in statement I alone are not sufficient to answer the question
C. if the data either in statement I alone or in statement Il alone are sufficient to answer the question
D. if the data given in both statements I and II together are not sufficient to answer the question

Answer

D

Explanation

From statement I: `R gt Q, R gt T , S gt R`
So, the arrangement in descending order of weights:
`underset(1)(S) gt underset(2)(R) gtunderset(3)(Q) gtunderset(4)(T) " "underset(1)(S) gt underset(2)(R) gtunderset(3)(T) gtunderset(4)(Q)`
But there is no information regarding P. So, statement I alone is not sufficient. From statement II: S `to` not the heaviest. But there is no information regarding P, Q R and T. So, statement II alone is not sufficient.
From I & II, we get P`to` heaviest.
So, the arrangement in descending order of weights:
`underset("(heaviest)")underset(darr)underset(1)(P)gt underset(2) (S)gt underset(3)(R)gt underset(4) (Q) gt underset("(lightest)")underset(darr)underset(5)(T)" or "underset("(heaviest)")underset(darr)underset(1)(P)gt underset(2) (S)gt underset(3)(R)gt underset(4) (T) gt underset("(lightest)")underset(darr)underset(5)(Q)`
So, either T or `Q to` lightest.
Therefore, the data in both statement I and II together are not sufficient to answer the given question.
