9.  A train 125 m long passes a man, running at 5 km/hr in the same direction in which the train is going, in 10 seconds. The speed of the train is: 

Your Answer: Option (Not Answered) Correct Answer: Option B Explanation:
= 45 km/hr. Let the speed of the train be x km/hr. Then, relative speed = (x  5) km/hr. x  5 = 45 x = 50 km/hr. Learn more problems on : Problems on Trains Discuss about this problem : Discuss in Forum 
10.  Two trains, each 100 m long, moving in opposite directions, cross each other in 8 seconds. If one is moving twice as fast the other, then the speed of the faster train is: 

Your Answer: Option (Not Answered) Correct Answer: Option C Explanation: Let the speed of the slower train be x m/sec. Then, speed of the faster train = 2x m/sec. Relative speed = (x + 2x) m/sec = 3x m/sec.
24x = 200
= 60 km/hr. Learn more problems on : Problems on Trains Discuss about this problem : Discuss in Forum

15. 


Your Answer: Option (Not Answered) Correct Answer: Option C Explanation: From II, let l = 4x, b = 6x and h = 5x. Then, area of the hall = (24x^{2}) m^{2}. From I. Area of the hall = 24 m^{2}. From II and I, we get 24x^{2} = 24 x = 1. l = 4 m, b = 6 and h = 5 m. Thus, area of two adjacent walls = [(l x h) + (b x h)] m^{2} can be found out and so the cost of painting two adjacent walls may be found out. Thus, III is redundant. Correct answer is (C).
