Two stations A and B are 200 km apart on a straight track. 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? Options
A) 02 p.m.	B) 06 p.m.	C) 10 p.m.	D) 12 p.m.	E) 11 p.m.
Explanation:   Assume both trains meet after 'p' hours after 7 a.m.   Distance covered by train starting from A in 'p' hours = 20p km   Distance covered by train starting from B in (p-1) hours = 25(p-1)   Total distance = 200   =&gt; 20x + 25(x-1) = 200   =&gt; 45x = 225   =&gt; p= 5   Means, they meet after 5 hours after 7 am, ie, they meet at 12 p.m.   Answer: 12 p.m.
