Q6) Ratio of the speeds of two trains is 4:7. What is the ratio of the distance travelled by these two
trains in 11 hours? 1) 4:3 2) 4:7 3) 7:11 4) 3:11
When time is same then, ratio of speed = ratio of distance = 4:7 Hence, option 2. Q7) A train running at a speed of 45 Km/hr crosses a pole in 8 seconds. Find the length of the train (in meters). 1) 100 m 2) 120 m 3) 160 m 4) 135 m  Hence, option 1. Q8) A train 240 m long passes a man, running at 7 Km/hr in the opposite direction in which the train is going, in 16 seconds. The speed of the train is: 1) 54 Km/hr 2) 61 Km/hr 3) 47 Km/hr 4) 65 Km/hr  Speed of the train = 54 - 7 = 47 Km/hr Hence, option 3.

Let y be the length of the tunnel  Hence, option 4. Q10) A car travelling at 3/5th of its actual speed covers 'c' Km in ‘t' hours. How much distance can be covered by this car in ‘2t' hours, by traveling at its actual speed? 
Let s be the actual speed.  i.e. 10c/3 is the distance travelled in 2t hours travelling at actual speed. Hence, option 3. |
