A train can travel 50% faster than a car. Both start from point A at the same time and reach point B 75 kms away from A at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is: Choose the correct choice from the following options.
A) 130 kmph B) 110 kmph C) 150 kmph D) 120 kmph E) 170 kmph
D   120 kmph   Let speed of the car be x kmph.   Then, speed of the train=(150/100)*x=(3/2)*x kmph   (75/x)-(75/(3/2x))=125/(10*60)   (75/x)-(50/x)=5/24   x = 25x24/5 = 120kmph.
