In each of the following questions, certain pairs of words are given, out of which the words in all pairs except one, bear a certain common relationship. Choose the pair in which the words are differently related?

6, 12, 20, 30, ?

In the following question, from the given alternative words, select the word which can be formed using the letters of the given word.
CAPITULATE

Directions: Study the following information to answer the questions.

Twelve people are sitting in two parallel rows containing 6 people each, in such a way that there is an equal distance between adjacent persons. In row-1 P, Q, R, S, T, and U are seated and all of them are facing south. In row-2 A, B, C, D, E and F are seated and all facing North. Therefore, in the given seating arrangement each member seated in a row faces another member of the outer row.
 S sits third to right of Q, either S or Q sits an extreme end of line. The one who faces Q sits second to right of E. Two people sits between B and F. Neither B nor F sits at an extreme end of the line. The immediate end of line.
 The immediate neighbour of B faces the person who sits third to left of P, R and T are immediate neighbours of the each other. C sits second to the left of A. T does not face the immediate neighbour of D.

Which of the following is true regarding T?

Direction: Read the following information carefully to give the answers to the questions based on it.
 Ten people A, B, C, D, E, F, G, H, I and J are sitting around a rectangular table at equidistance (but not necessarily in the same order) in such a way that one of them is sitting at each of the corners, one of them is sitting at each of the shorter sides and two of them are sitting at each of the longer sides. Half of them are facing the centre and half of them are facing away from the centre.
 D is not sitting on the shorter side of the table. A sits third to the right of F. I is not an immediate neighbour of B or F but sits on the immediate right of C, who is facing away from the centre and sitting at one of the corners of the table. H is sitting to the immediate left of J. D is sitting third to the left of J. I sits fourth to the left of A. E sits to the immediate left of D and is not an immediate neighbour of C. A and E are facing the same direction. D and G sit diagonally opposite to each other but not necessarily sitting at the corners. D and G are facing opposite directions. H and I are facing the same direction. I do not sit on one of the shorter sides 

Four of the following five are alike in a certain manner and hence form a group. Find the one who does not belong to that group?
