The distance between two cities A and B is 600 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 most appropriate option:
A) 09 AM
B) 07 AM
C) 01 PM
D) 05 PM
E) 03PM
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] = 600.   Therefore, 60x + 75(x-1) = 600.   =&gt; x=5.   So,they meet at (8+5) i.e, 1p.m.   Answer: 01 PM)
