Answer: Option E. -> Cannot be determined.

If Sujit entered before Suraj then the number of people will be 15 + 1(Sujit) + 7 + 1(Suraj) + 20 = 44.If Suraj entered before Sujit then number of people will be 7 + 1(Suraj) + 7 + 1(Sujit) + 12 = 28.So, the number of people in the theater cannot be determined.

Question 44. P, Q, R, S, T and U are six cities which are in a row in the same order. A bus, b1 travels from P to U and another bus b2 travel from U to P. The bus b1 reaches S at 10:40 and bus b2 reaches Q at 10:35 if the travel time between any two adjacent cities is 40 minutes and the stoppage time at each city is 15 minutes, then at what time do they start at their respective destinations?

Discuss Question

Answer: Option C. -> 8:10, 7:10

The bus b1, which started at P, reached S at 10:40, passing through the intermediary cities Q and R.The time taken to travel from P to S= 3 * 40 + 2 * 15 = 150minute (journey)+(stoppage)
= 2 hrs 30 minutes.Hence, b1 started at 10:40 - 2:30 = 8:10 at P.b2 reached Q, starting at U, through the city T, S and R.The time taken by it to reach S = 4 * 40 + 3 * 15 = 205 minutes
= 3 hr 25 minutes.Hence, b2 started at, 10:35 - 3:25 = 7:10, at U.

Question 45. A, B, C, D, E and F are six cities which are collinear in the same order. The distance between any two adjacent cities is equal. A bus starts at A for city F. It takes 25 minutes for the bus to travel from one city to another and stops for 5 minutes at each place. If the bus reaches E at 8:55, then at what time did it reach station B?

Discuss Question

Answer: Option A. -> 7:25

Between B and E there are two intermediary stations C and D. For traveling from B to C, from C to D and from D to E it takes 3 * 25 = 75 minutes. At each of C and B it halts of 5 minutes. Hence, the time taken to reach E after starting at B is 85 minutes. i.e. one hour 25 minutes. Hence, it started at 7:30 at B.
=>it reached B at 7:25.

Question 46. Six persons - A, B, C, D, E and F are sitting around a circular table. B is sitting to the immediate right of E. C is not sitting next to F. F is sitting opposite B and D is sitting opposite E. Who is sitting to the immediate left of D?

Discuss Question

Answer: Option C. -> C

C is not sitting next to F. Therefore, the final arrangement is as follows.

C is sitting to the immediate left of D.

Question 47. P through V are seven persons sitting around a circular table. V is sitting to the left of P, who is sitting to the left of S. V is sitting to the right of U. R is sitting between T and U. Who is sitting to the right of Q?

Answer: Option B. -> T

V is sitting to the left of P, who is sitting to the left of S.

V is sitting to the right of U. R is sitting between T and V. Therefore, The final arrangement as follows.

T is sitting to the right of Q.

Question 48. Eight persons of a family, A, B, C, D, E, F, G and H are sitting around a circular table facing the center but not necessarily in the same order.

Discuss Question

Answer: Option A. -> C

From I and II we say that F is player and seated opposite D. It is given that G is sitting third left of the actor, then we have two possible arrangements. Also H is the actor.Case I: G is second to the left of F, who is left of Actor.Case II: G is sitting to the left of F, who is second left of Actor.Case III: G is second to the right of F, who is third left of Actor.Case IV: G is third to the right of F, who is third left of Actor.We can say that the actor is not opposite to the scientist and in II and IV it is given that B is a scientist and sitting adjacent to E.The above arrangement is not possible for case II and IV.Hence case II and IV is eliminated.Case III is eliminated as B is adjacent to E and it is not possible in this case.In case I, the above arrangement is E is to the right of the actor, who is to the left of the scientist.From III and IV we can say that C is not an actor and not adjacent to D, then C is to the left of F, who is player.Also we can say that G is a businessman, as it is given that C is sitting adjacent to businessman.In III, it is given that the engineer and the doctor are adjacent to each other. The possible arrangement is D is an Engineer and A is Doctor, as we know that A is not an actor, only option left A is a doctor. Now, we can say that E is a teacher as it is given that E is not a lawyer then only option for E is a Teacher and C is a lawyer.The final arrangement as follows:

C is a Lawyer.

T is sitting between R and S.

Discuss Question

Answer: Option C. -> R is sitting between S and V.

S is sitting opposite Q and Q is sitting the right of W.

T is sitting adjacent to S and P. So, T is in between S and P. P is the sitting to the right of U.

V is sitting opposite to P. So, the final arrangement is as follows.

So, R is sitting between V and S is true.

Question 50. Eight persons P, Q, R, S, T, U, V and W are sitting around a circular table. Not all of them are facing the center. P is second to the right of Q who is to the right of V. U is sitting in a position opposite W, who is third to the right of R. S is opposite V and no two persons facing towards the center of the table are adjacent to each other. The number of persons sitting in a position facing away from the center of table is less then five.What is position of Q with respect to W?

Discuss Question

Answer: Option A. -> Immediate left

Given that the number of persons not facing the center of the table is less than five. Also, no two persons are facing the center of the table. So we can conclude that the persons sitting adjacent to each other face different directions.
Case(i)Let V face the center.
Given Q is to the right of V and P is opposite to T. Also W is third to right of R and is opposite U. Implies V is to the left of P.The arrangement is as follows.

Case(ii)Let V face away from the center. From the given clues we can say that V is to the left of P.The final arrangement is as follows.

Q is to the immediate left of W
