The distance between two cities A and B is 330 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? Answers:  A) 10 a.m  B) 10.30 a.m  C) 11 a.m  D) 11.30 a.m  E) None of these
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] = 330.   Therefore, 60x + 75(x - 1) = 330.   =&gt; x = 3.   So,they meet at (8 + 3) i.e, 11a.m.   Answer: 11 a.m
