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 ?	Answers: A) 9 a.m B) 10 a.m C) 10-30 a.m D) 11 a.m E) None
Solution   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   Answer 10 a.m
