Answer 1

The correct option is B IX

Seven students P, Q, R, S. T, V and W study in standard IV to X. Each of them has their own favourite subject.
T studies in VIII standard and likes Hindi.

T $\to$ VIII standard $\to$ Hindi

The one who likes Science studies in X standard.

? $\to$ Science $\to$ X standard.
S studies in IV standard.
W like Sanskrit.
P does not study in X standard.
The one who likes Geography studies in V standard.
Q studies in VII standard.
R likes English.

Now, we write the above information in tabular form as
$\begin{array}{ccc}Students& Standard& Favouritesubjects\\ P& \dots \dots & \dots \dots \\ Q& VII& \dots \dots \\ R& \dots \dots & English\\ S& IV& \dots \dots \\ T& VIII& Hindi\\ V& \dots \dots & \dots \dots \\ W& \dots \dots & Sanskrit\end{array}$
Their are four sections left and there are V, VI, IX, X.
It is given that,
P does not study in standard X and the one who studies in standard X likes Science.
So, it is clear that V studies in standard X and his favourite Subject is Science.
V $\to$ Science $\to$ Standard X
Now, we are left with three standards V, VI, IX
The one who likes Geography studies in standard V, so it is clear that P studies in standard V and studies Geography.
P $\to$ Geography $\to$ Standard V
Now, we are left with two standards VI and IX. It is given that, R does not study in either V or IX. So, R studies in standard VI and likes English.
R $\to$ standard VI $\to$ English
Now, we are left with only one standard. So it is clear that
W $\to$ standard IX $\to$ Sanskrit
Now, we are unclear about the favourite subjects of Q and S.
It is given that Q does not like Mathematics.
So, it is clear that Q likes History and S likes Mathematics.
Now, we arrange the above information and show them in tabular form:-

$\begin{array}{ccc}Students& Standard& Favouritesubjects\\ P& V& Geography\\ Q& VII& History\\ R& VI& English\\ S& IV& Mathematics\\ T& VIII& Hindi\\ V& X& Science\\ W& IX& Sanskrit\end{array}$

W study in standard IX.
