The distance between two cities A and B is 1410 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?	Choose the correct choice from the following options.
A) 09 PM B) 07 PM C) 11 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] = 1410.   Therefore, 60x + 75(x-1) = 1410.   =&gt; x=3.   So,they meet at (8+11) i.e, 7 PM.   Answer: 07 PM
