Previous Year Question (PYQs)



Q, R, S, T, U and V are seated in a straight line facing North. S is second to the right of T and T is second to the right of Q. R is to the left of Q and second to the left of V. What is Q’s position with respect to S?





Solution

Let positions be 1 (leftmost) to 6 (rightmost). $T$ is second right of $Q$ ⇒ $T=Q+2$. $S$ is second right of $T$ ⇒ $S=T+2=Q+4$. So $Q$ can be 1 or 2. Try $Q=2$ ⇒ $T=4$, $S=6$. $R$ is left of $Q$ and 2 left of $V$ ⇒ take $R=1$, then $V=3$ (fits). Arrangement: $1\!:\!R,\ 2\!:\!Q,\ 3\!:\!V,\ 4\!:\!T,\ 5\!:\!U,\ 6\!:\!S$. Thus $Q$ is **fourth to the left** of $S$.
