Seven colleagues — Uma, Qadir, Sana, Tarun, Payal, Rohan and Vikram — sit in a single row of seven chairs, all facing north. Vikram sits at one of the two ends. Exactly one person sits between Vikram and Payal. Tarun sits immediately to the left of Payal. Qadir is second from the left end. Rohan sits somewhere between Payal and Vikram. Uma does not sit next to Tarun. How many people sit between Qadir and Vikram?

Question

Accepted Answer

Four. Order from the left: Uma, Qadir, Sana, Tarun, Payal, Rohan, Vikram. (If Vikram were at the left end, Payal would be third and Tarun second, clashing with Qadir; so Vikram is at the right end, Payal fifth, Tarun fourth, Rohan sixth. Uma can't be third, next to Tarun, so Uma is first and Sana third.) Between Qadir (second) and Vikram (seventh) sit Sana, Tarun, Payal and Rohan — four people.
