Each of the questions below consists of a statement and/or 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. Read both the statements and -
Give answer 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.
Give answer 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.
Give answer c: if the data either in Statement I or in Statement II alone are sufficient to answer the question.
Give answer d: if the data even in both Statements I and II together are not sufficient to answer the question.
Give answer e: if the data in both Statements I and II together are necessary to answer the question.
(Caution : Do not hasten to mark the answer unless you consider both the Statements carefully).
A, B, C and D made their project presentation, one on each day, on four consecutive days but not necessarily in that order. On which day did ‘C’ make his presentation ?
I. The first presentation was made on 23rd, Tuesday and was followed by ‘D’s presentation
II. ‘A’ did not make his presentation on 25th and one of them made his presentation, between that of A’s and B’s.
Clearly each statement alone is not sufficient as there is not enough data in each of them, but when both are combined, we get :
The first presentation was made on 23rd, Tuesday and was followed by ‘D’s presentation.
=> The project presentation continued from 23rd to 26th from Tuesday till Friday and D presented on Wednesday.
‘A’ did not make his presentation on 25th and one of them made his presentation, between that of A’s and B’s.
=> A presented on the first day and B on Thursday.
Thus, C made his presentation on Friday.
$$\therefore$$ Both statements together are sufficient.
