Answers
Given:
Six lectures on areas like Leadership, Decision Making, Quality Circles, Motivation, Assessment Centre and Group Discussion.
Days through which the lectures are organised - Monday to Sunday
To find:
The day on which Leadership lecture will be organised.
No. of lectures organised between Motivation and Quality Circle.
The pair of lectures organised on the first and last day.
Solution:
Let L, D, Q, M, A, G represent Leadership, Decision Making, Quality Circles, Motivation, Assessment Centre and Group Discussion.
First we list the days from Monday to Sunday. It is given that the lecture on D will be organised on Friday and the lecture on Q will be organised on Wednesday.
Wednesday - Q
Friday - D
It is also given that Q should not be followed by G. Hence, G is not on Thursday. There should be a gap of two days between G and L.
M should be organised immediately after A.
There will be no lecture one day and that is not Saturday. Just before this day, the lecture on G is organised.
If this day is Monday, A and M cannot be organised one after the other. So, it's not Monday.
If the 'no lecture day' is Tuesday, then G will be organised on Monday and hence L on Wednesday. But that is not possible since Q is already scheduled for Wednesday. So, Tuesday is not the day.
If the 'no lecture day' is Thursday, on Wednesday G will be organised. But that is not possible since Q is already scheduled for Wednesday. So, Thursday is not the day.
If the 'no lecture day' is Sunday, then G is scheduled for Saturday and two days earlier, i.e., on Thursday L will be organised. Hence, Sunday is 'the 'no lecture day'.
Wed - Q
Thu - L
Fri - D
Sat - G
Sun - no lecture
Now, the remaining days are Monday and Tuesday. A will be on Monday and M will be on Tuesday because M should be organised immediately after A. Hence,
Mon - A
Tue - M
Wed - Q
Thu - L
Fri - D
Sat - G
Sun - no lecture
50) Hence, L will be organised on Thursday. Option (D) None of these is the correct answer.
51) Between M and Q, no lectures are organised.
52) On the first day A is organised and on the last day G is organised. Option (d) none of these is the correct answer.
The following is the order of lectures:
Monday - Assessment Centre
Tuesday - Motivation
Wednesday - Quality Circles
Thursday - Leadership
Friday - Decision Making
Saturday - Group Discussion
Sunday - no lecture
50) Option (D) None of these is the correct answer.
51) Between M and Q, no lectures are organised.
52) Option (d) none of these is the correct answer.
