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.
On a T.V. Channel, four serials A, B, C and D were screened, one on each day, on four consecutive days but not necessarily in that order. On which day was the serial C screened ?
I. The first serial was screened on 23rd, Tuesday and was followed by serial D.
II. Serial A was not screened on 25th and one serial was screened between serials A and B.

Options

A. (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. (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. (C). if the data either in statement I alone or in statement Il alone are sufficient to answer the question
D. (D). if the data in both statements I and II together are necessary to answer the question.

Answer

D

Explanation

From statement I:
Serials `overset("screened on")rarr` 23rd, 24th, 25th and 26th.
So, serial `D overset("screened on")rarr` 24th, Wednesday i.e. second.
But there is no information regarding C. So, statement I alone is not sufficient.
From statement II :
One serial `overset("screened between")rarr` serials A and B.
Serial A `overset("not screened on")rarr`25th
So, serial `A overset("screened on")rarr` 23rd, Tuesday i.e. first.
Serial B `overset("screened on")rarr` 25th, Thursday i.e. third.
But there is no information regarding C. So, statement II is not sufficient.
From I & II, we get
Serial C `overset("screened on")rarr` 26th, Friday i.e. Fourth.
Therefore, the data in both statements I and II together are necessary to answer the given question.
