(ii) $S$ and $U$ get diagonally opposite flats.
(iii) $R$,next to $U$,gets a South-facing flat and $T$ gets a North-facing flat.

Among six friends $L, M, N, P, Q$ and $S,$ each having a different height,$N$ is taller than $Q$ and $P$ but shorter than $M.$ $P$ is taller than only $Q$ while $S$ is shorter only than $L.$ Which of the following pairs represents the tallest and the shortest among the six friends?

$X$ and $Y$ start moving towards each other from two places $200 \, m$ apart. After walking $60 \, m$,$Y$ turns left and walks $20 \, m$,then turns right and walks $40 \, m$. He then turns right again and comes back to the road on which he had started walking. If $X$ and $Y$ walk with the same speed,what is the distance between them now? (in $m$)
