Direction (17–21): Read the given information carefully and answer the question. Ten people G, H, I, J, K, L, W, X, Y and Z live in a building with four floors. Each floor has three flats—Flat 1, Flat 2, and Flat 3—from left to right. The ground floor is numbered Floor 1 and the topmost floor is Floor 4. Each flat is built such that Flat 1 of Floor 2 is directly above Flat 1 of Floor 1, and so on. The two flats in which no one lives are on an even-numbered floor and in an even-numbered flat. G does not live on an even-numbered floor and in an even-numbered flat. W lives in the flat just above H. The flat between K and X is vacant, and K lives in one of the flats above X. L lives in an odd-numbered flat which is to the left of X. Z and Y live on the same floor, and no one else lives on that floor. G lives on a floor and in a flat just above W’s floor and flat.

Directions (1-5): Study the following information carefully and answer the questions that follow. In the given figure, the four line segments 1, 2, 3 and 4 are RA, SB, TC and UD respectively. The lengths of the lines are 39 m, 25 m, 27 m and 49 m respectively. Six people Mohan, Sohan, Rohan, Ankit, Vinit and Sumit are standing in line RA. All of them are facing north. The distance between them increases in multiples of 7 from the left end (i.e., if Mohan is at the left end of the line at point R, then the remaining people will stand at distances of 7 m, 14 m, 21 m, and so on from the end). Mohan is standing at the left end of the line. Two persons are standing between Mohan and Sohan. Rohan stands second to the left of Sohan. Sumit is an immediate neighbour of Rohan. Only one person stands between Sumit and Ankit. Similarly, six people Anita, Ambika, Amrita, Aanchal, Arpita and Ajita are standing in line UD. All of them are facing south. The distance between them increases in multiples of 9 from the right end (i.e., if the first person is at the right end of the line at point U, then the remaining people will stand at distances of 9 m, 18 m, 27 m, and so on from point U). Amrita is standing at the 3rd position from the right end. Arpita is an immediate neighbour of Amrita. Two people are standing between Arpita and Ajita. More than three persons stand between Ajita and Anita. Aanchal stands immediately to the left of Ajita. Ambika and Arpita are immediate neighbours. Point S and point T are the left ends of the rows in lines SB and TC.
