Direction: Study the following information carefully and answer the given questions.

Six persons P, Q, R, S, T, and U are living in a three-storey building such that ground floor is numbered as 1, above it is floor 2 then top floor is numbered as 3. Each of the floor has 2 flats in it as flat-X and flat-Y. FlatX of floor-2 is immediately above flat-X of floor-1 and immediately below flat-X of floor-3. In the same way flat-Y of floor-2 is immediately above flat-Y of floor-1 and immediately below flat-Y of floor-3. Flat-X is in west of flat-Y. They all are from different cities.

The one who is from Kolkata lives immediately above U. S lives to the west of U. P and the one who is from Kolkata do not live on the same floor. Neither S nor Q is from Bangalore. U is either from Pune or from Agra. There is one floor between Q and the one who is from Delhi who lives above Q. T does not live in flat Y. The one who is from Mumbai lives on the same floor on which the one who is from Agra lives. P lives on an odd numbered floor in flat X.

Who lives on the bottom most floor?

Direction: Study the information given below carefully and answer the questions that follow.
 There are two persons Basu and Vinay, who walked from different point to reach a common point A.
 Basu started walking from point C in north direction. After walking 3m he turns right from point E, he then walks for another 3m and turns right from point D. He then walks for 7m and then turns left from point G and walks for 5m till point F. He then turns left and walks for 3m and then turns right from point N and walks for 6m till point A.
 Vinay started walking from point X in north direction. After walking 9m he turns left from point Z and walks for 6m and then turns left from point Y. He then walks for 4m and then turns left from point P and walks for 9m till point Q. He then turns right and walks for 2m till point A.

There are as many persons buy things before U as after V. More than three persons buy things between W and X who buy things just after P. Y buy things before Z and after R. No one buy things after T. Y buy things just after V. U buys after Q.
