Q: A train with 120 wagons crosses Arun who is going in the same direction, in 36 seconds. It travels for half an hour from the time it starts overtaking the Arun ( he is riding on the horse) before it starts overtaking the Sriram( who is also riding on his horse) coming from the opposite direction in 24 seconds. In how much time (in seconds) after the train has crossed the Sriram do the Arun meets to Sriram? 5722 05b5cc7d0e4d2b419777511e5

Answer : 3. "3576 sec"
Explanation :
Answer: C) 3576 sec Explanation: Let the length of the train be L metres and speeds of the train Arun and Sriram be R, A and S respectively, then LR-A=36 ---------- (i) and LR+K=24 ---------(ii) From eq.(i) and (ii) 3(R - A ) = 2 (R + K) ⇒ R = 3A + 2K In 30 minutes (i.e 1800 seconds), the train covers 1800R (distance) but the Arun also covers 1800 A (distance) in the same time. Therefore distance between Arun and Sriram, when the train has just crossed Sriram = 1800 ( R - A) - 24 ( A + K) Time required = 1800(R-A)-24(A+K)(A+K) = (3600 - 24) = 3576 s

Q:Each question below is followed by two statements A and B. You have to determine whether the data given in the statement is sufficient for answering the question. You should use the data and your knowledge of Mathematics to choose the best possible answer.
Give answer (A) if the statement A alone is sufficient to answer the question, but statement B alone is not sufficient.
Give answer (B) if the statement B alone is sufficient to answer the question, but statement A alone is not sufficient.
Give answer (C) if both statements A and B together are needed to answer the question.
Give answer (D) if either the statements A alone or statement B alone is sufficient to answer the question
Give answer (E) if you cannot get the answer from the statements A and B together, but need even more data.
X, Y and Z are three consecutive even numbers (not necessarily in this order). What is the sum of these numbers?
A. The difference between X and Z is 4.
B. One-third of Y is 14.
