Question

Three of the five students allocated to a hostel put in special requests to the warden. Given the floor plan of the vacant rooms, select the allocation plan that will accommodate all their requests. Request by X: Due to pollen allergy, I want to avoid a wing next to the garden. Request by Y: I want to live as far from the washrooms as possible, since I am very sensitive to smell. Request by Z: I believe in Vaastu and so want to stay in the South-west wing. The shaded rooms are already occupied. WR is washroom.

Correct answer (D) [figure] Solution Reading the compass. In every plan the compass arms point to the corners: N to the top-left, E to the top-right, S to the bottom-right and W to the bottom-left. So the four sides of the building are the wings: top side: North-east wing right side: South-east wing (the side with the Garden) bottom side: South-west wing left side: North-west wing The washrooms (WR) are at the two left corners. Requests. Z wants the South-west wing, i.e. a room on the bottom side. X must avoid the wing next to the garden, i.e. must not be on the right side. Y wants to be as far from the washrooms as possible, i.e. on the right side (the washrooms are on the left). Checking the options. (A) Z is on the left side (North-west wing). Fails. (B) Z is on the left side, and X is in the top-right room next to the garden. Fails. (C) Z is on the top side (North-east wing). Fails. (D) Z is on the bottom side (South-west wing), X is on the bottom side away from the garden, and Y is on the right side, farthest from the washrooms. All three requests are met. Answer: (D) Turn this into a strength. Explore AI-powered practice and doubt support with Success Tracker.
