The distance between two cities A and B is 870 Km. A train starts from A at 8 a.m. and travel towards B at 60 km/hr. Another train starts from B at 9 a.m and travels towards A at 75 Km/hr. At what time do they meet?	Select the correct option
A) 09 PM  B) 07 PM  C) 03 PM  D) 05 AM  E) 03 AM
Explanation:   Suppose they meet x hrs after 8 a.m   then,   [Distance moved by first in x hrs] + [Distance moved by second in (x-1) hrs] = 870.   Therefore, 60x + 75(x-1) = 870.   =&gt; x=7.   So,they meet at (8+7) i.e, 15 =&gt;3PM   Answer: 03 PM)
