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? Choose the correct answer: A) 10 am B) 11 am C) 12 pm D) 1 pm 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   So, 60x+75(x-1) = 330   x=3.   So,they meet at (8+3). i.e 11a.m.   Answer: 11 am
