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
