Question 48 Back to Exercise
Questions : 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 serials C screened.
Statements : 

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 serial A and B.

  • A I alone is sufficient while II alone is not sufficient.
  • B II alone is sufficient while I alone is not sufficient.
  • C Either I or II is sufficient.
  • D Neither I nor II is sufficient.
  • E Both I and II are sufficient. Correct
Correct Answer: Option E

From I, we know that the serial were screened on 23rd, 24th, 25th and 26th.

Clearly, D was screened second i. e. on 24th, Wednesday.

From II, we know that one serial was screened between A and B. So, A and B were screened first and third, i. e. on 23rd and 25th. But, A was not screened on 25th.

So, A was screened on 23rd and B on 25th. Thus, C was screened on 26th, Friday.
