WBCS Mains 2018 Official Paper-VI

$P$, $Q$, $R$, $S$, and $T$ are sitting around a circular table facing the center. $R$ is to the immediate right of $P$ and is second to the left of $S$. $T$ is not between $P$ and $S$. Who is second to the left of $R$?

Two buses start from opposite points on a straight main road that is $150\text{km}$ apart. The first bus runs for $25\text{km}$, takes a right turn, and runs for $15\text{km}$. It then turns left, runs for another $25\text{km}$, and then takes a turn to head back to reach the main road. In the meantime, due to a minor breakdown, the second bus has run only $35\text{km}$ along the main road. What is the distance between the two buses at this point?

Consider the following statements:

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