$(iii)$ $R$ went to Bangalore by car and $Q$ went to Calcutta by aeroplane.
$(iv)$ $S$ travelled by boat whereas $T$ travelled by train.

$(i)$ Eleven students,$A, B, C, D, E, F, G, H, I, J$ and $K$ are sitting in the first row of the class facing the teacher.
$(ii)$ $D$,who is to the immediate left of $F$,is second to the right of $C$.
$(iii)$ $A$ is second to the right of $E$,who is at one of the ends.
$(iv)$ $J$ is the immediate neighbour of $A$ and $B$ and third to the left of $G$.
$(v)$ $H$ is to the immediate left of $D$ and third to the right of $I$.
Which of the following groups of friends is sitting to the right of $G$?

Clearly,$Q$ is neither a hockey player nor a chess player. So,he must be a football player and thus cannot be a lady. $T$ is a husband (not a lady) and so must be a chess player.

$P -$ unmarried lady,does not participate in games.
$Q -$ brother of $R$,football player.
$R -$ hockey player,$T$'s wife.
$S -$ unmarried lady,does not participate in games.
$T -$ husband of $R$,chess player.
