The distance between two cities A and B is 330 km. A train starts from A at 8 a.m. and travels 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) 12 a.m	B) 13 a.m	C) 14 a.m	D) 11 a.m	E) 16 a.m
D   11 a.m   Suppose they meet x hrs after 8 a.m. Then,   (11 a.mistance moved by first in x hrs) + [11 a.mistance moved by second in (x - 1) hrs] = 330   60x + 75(x - 1) = 330 =&gt; x = 3   So, they meet at (8 + 3) i.e., 11 a.m.
