Question - 5:Two trains of equal lengths take 10 seconds and 15 seconds respectively to cross a telegraph post. If the length of each train be 120 metres, in what time (in seconds) will they cross each other travelling in opposite direction??

1. 10
2. 12
3. 15
4. 20

Show/Hide Answer

Answer = B - 12
Explanation: Speed of the first train = ( 120 /10) m/sec = 12 m/sec.

Speed of the second train = ( 120 /15) m/sec = 8 m/sec.

Relative speed = (12 + 8) = 20 m/sec.

Therefore Required time = [ (120 + 120) /20] sec = 12 sec.

Question - 8:Two stations A and B are 110 km apart on a straight line. One train starts from A at 7 a.m. and travels towards B at 20 kmph. Another train starts from B at 8 a.m. and travels towards A at a speed of 25 kmph. At what time will they meet ??

1. 9 a.m
2. 10 a.m
3. 10-30 a.m
4. 11 a.m

Show/Hide Answer

Answer = B - 10 a.m
Explanation: Distance covered by A in x hours = 20 x km
Distance covered by B in (x - 1) hours = 25 (x - 1) km
= 20x + 25 (x - I)
= 110
= 45x = 135
x = 3. So, they meet at 10 a.m
