B) 30 seconds
C) 40 seconds
D) 45 seconds
E) 36 seconds
Correct Answer: D
Solution :
Length of train A \[=90\times 12\times \frac{5}{18}\] = 300m Now, length of train B \[=300\times \frac{150}{100}=450m\] \[\therefore \]Time taken by Train B to cross the pole \[=\frac{450\times 18}{36\times 5}=45\]SecondsYou need to login to perform this action.
