    Answer : Option C

    Explanation :

    Let speed of the car be x kmph.

     

    Then, speed of the train =\([ \frac { 3 } { 2 }X]kmph\)

     

    \(\frac { 75 } { X} \)-\(\frac { 75 } { (3/2)X} \)=\(\frac { 125 } { 10*60} \)

     

     \(\frac { 75 } { X} \)-\(\frac { 50 } { X} \)=\(\frac { 5 } {2 4 }\)

     

     x =[\([\frac {25*24 } { 5 }]\)=120kmph
