Two stations P and Q are 290 km apart on a straight track. One train starts from P at 7 a.m. and travels towards Q at 20 kmph. Another train starts from Q at 8 a.m. and travels towards P at a speed of 25 kmph. At what time will they meet?	Pick.
A) 10 am
B) 12 am
C) 10.30 am
D) 12.30 pm
E) 2 pm
Assume both trains meet after x hours after 7 am   Distance covered by train starting from P in x hours = 20x km   Distance covered by train starting from Q in (x-1) hours = 25(x-1)   Total distance = 290   =&gt; 20x + 25(x-1) = 290   =&gt; 45x = 315   =&gt; x= 7   Means, they meet after 7 hours after 7 am, ie, they meet at 2 pm   Answer is 2 pm.
