Question
Using which of the following material does floor 4 was
built? Study the following information carefully and answer the questions given below. Nine floors of a building are made of nine different flooring materials viz. Timber, Vinyl, Bamboo, Cork, Natural, Rubber, Mastic, Tiles and Wood, but not necessarily in the same order. The lowermost floor is numbered as 1 and the floor immediately above it is numbered as 2 and so on. Only four floors are there between the timber floor and the bamboo floor which is immediately above the Vinyl floor and below the timber floor. The number of floors above the Vinyl floor is one more than the number of floor below the tiles floor. Only two floors are there between the tiles floor and the wood floor. The number of floors between the wood floor and the bamboo floor is the same as the number of floors between the vinyl floor and the rubber floor. One of the even numbered floors is made of natural floor and is immediately above the mastic floorSolution
1) Only four floors are there between the timber floor and the bamboo floor which is immediately above the Vinyl floor and below the timber floor. The number of floors above the Vinyl floor is one more than the number of floor below the tiles floor 3) One of the even numbered floors is made of natural floor and is immediately above the mastic floor. Hence, case 3 gets eliminated.
