the guys who hv give the last answer as V, i think u guys hvnt considered the fact that the bus is traveling with a diff avg speed btwn P to S and T to Q. and the two avg speeds are v m/s and 2v m/s.
So, one wld take half the time than other. but our original constraint is that it must take the same time to reach there.

Hence, the arrangement wld look something like this.

TQPUSRV

T to Q, it will travel with v m/s taking say 1 hr.
P to S, with 2v m/s again taking one hour.

@Enceladus I considered T to Q and P to S traveling at same speeds that is V m/s and they are at equal distance too

And the arrangement I got is
TQPSUVR

Is there is anywhere I am wrong???

bhai options wld hv helped. aese bohot ambiguous ho ra h.

still my take is
1)T was the first stop.
2)R was the last bus stop.
3)S was before R.

Pls confirm. si ni h toh options de, firse try karta hun
