Which day will the lecture F be organised ?

Options

A. Thursday
B. Friday
C. Saturday
D. Sunday

Answer

A

Explanation

According to the given information :
From (v), we get
Lecture `B overset("organised on")rarr` Tuesday ….(vi)
From (iii), (iv) & (v), we get
Lecture `D overset("organised on")rarr` Sunday. …(vii)
So, Lecture `E overset("organised on")rarr` Wednesday. ....(viii)
From (iv) & (vii), we get
No Lecture ` overset("organised on")rarr` Monday. ....(ix)
From (i) & (ii), we get
Lecture `F overset("organised on")rarr` Thursday. ....(x)
So, Lecture `C overset("organised")rarr` immediately after lecture F i.e. on Friday. ...(xi)
By elimination, we get
Lecture `A overset("organised on")rarr` Saturday. ...(xii)

By analysing the above table, it is clear that Lecture `F overset("organised on")rarr` Thursday.
