$(A)$ $P, Q, R, S$ and $T$ are sitting in a circle facing the centre.
$(B)$ $R$ is immediate left of $T.$
$(C)$ $P$ is between $S$ and $T.$

Five men $A, B, C, D$ and $E$ read a newspaper. The one who reads first gives it to $C.$ The one who reads last had taken from $A. E$ was not the first or last to read. There were two readers between $B$ and $A.$ Who read the newspaper last?

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. Hence,$R$ must be a hockey player,and therefore she must be a lady and $T$'s wife. So,the information can be summarised as follows:
$P -$ 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.
Who is the chess player?
