EEight Directions (Q6–Q10) : Nine candidates who had been called for the document veri cation stage of a recruitment held by a bank were made to occupy a single row of nine chairs in the waiting hall of the regional o ce, and the register kept by the attendant at the door records their places and the way in which each of them was turned, as follows. Study the following information with care and then answer the questions that follow. Nine persons – Abhilasha, Chintamani, Elangovan, Firdausi, Gyanwati, Nishikant, Rukmangad, Tarachandra and Zubeida – are seated in a single straight row at equal distances from one another. The row runs from the west to the east, the westernmost chair being reckoned as the rst chair of the row and the easternmost as the ninth.

(i) Abhilasha and Zubeida occupy the two extreme ends of the row, Abhilasha sitting at the western end of it and Zubeida at the eastern end. (ii) Abhilasha faces towards the south and Zubeida faces towards the north. (iii) Chintamani sits second to the west of Firdausi. (iv) Exactly ve of the persons sit between Chintamani and Tarachandra. (v) Elangovan is an immediate neighbour of Chintamani and is also an immediate neighbour of Firdausi.
