C) \[\text{120 }km/hr.\]
D) \[\text{100 }km/hr.\]
Correct Answer: C
Solution :
Total distance travelled by train. = Length of platform + Length of train \[=550+550=1100\]meters Speed of trains \[=\frac{\text{Distance}}{\text{Time}}=\frac{1100}{33}m/\sec .\] \[=\frac{1100}{33}\times \frac{18}{5}\,\,=\underline{\mathbf{120km/hr}\mathbf{.}}\]
