Choose the correct sequence from the options given below:
Solution
Since only S5 precedes S1, S5 is on Monday and S1 on Tuesday. Since nothing follows S6, S6 is on Saturday.
S2, S3 and S4 occupy Wednesday to Friday. S2 is not on Wednesday and comes before S4, so S3 is Wednesday, S2 Thursday, S4 Friday.
Thus S1, S3, S4, S6 gives (D), (C), (B), (A).
