Two trains of equal length are running on parallel lines in the same direction at 46 km/hr and 36 km/hr. If the faster train passes the slower train in 36 seconds,what is the length of each train?
Choose the correct choice from the following.
A) 25	B) 30	C) 50	D) 75	E) 40
Assume the length of each train = x   Total distance covered for overtaking the slower train = x+x = 2x   Relative speed = 46-36= 
<gadget id="calculator">46-36</gadget>
<output>10</output>
10km/hr= (10×10)/36 = 100/36 m/s   Time = 36 seconds   2x/ (100/36) = 36   =&gt; (2x × 36 )/100 = 36   =&gt; x = 50 meter   Answer is 50.
