• B. Q - III - Green
• C. S - I - Black
• D. T - V - Yellow
• E. None of the above

Answer 1

The correct option is E None of the above

There are six students of a school P, Q, R, S, T and M. They study in class I - VI. Each of them has a favourite colour.
According to the question:-
Q likes Black.
P studies in class II. M likes Blue.
S likes Pink and studies in class I.
Now, the information can be represented in tabular form as.
$\begin{array}{ccc}Students& Classes& Favouritecolours\\ P& II& \dots \dots \\ Q& \dots \dots & Black\\ R& \dots \dots & \dots \dots \\ S& I& Pink\\ T& \dots \dots & \dots \dots \\ M& \dots \dots & Blue\end{array}$
The one who likes yellow studies in class VI and R does not study in class VI, so it is clear that, T studies in class VI.
T $\to$ Class VI $\to$ Yellow
Q does not study in class IV or V. It means that, Q study in class III.
The one who studies in class IV does not like green and M does not study in class IV.
So, R $\to$ Class IV $\to$ ?
Definitely M studies in class V.
The one who studies in class IV does not like green and R's favourite colour is red.
So, P's favourite colour is green. Now, the tabular form of the information:-
$\begin{array}{ccc}Students& Classes& Favouritecolours\\ P& II& Green\\ Q& III& Black\\ R& IV& Red\\ S& I& Pink\\ T& VI& Yellow\\ M& V& Blue\end{array}$

None of the above combination is true.
