Question : The speeds of two trains are in the ratio 6 : 7. If the second train runs 364 km in 4 hours, then the speed of the first train is:
Option 1: 60 km/hr
Option 2: 72 km/hr
Option 3: 78 km/hr
Option 4: 84 km/hr
Correct Answer: 78 km/hr
Solution : The ratio of the speed of two trains = 6 : 7 Speed of the second train = $\frac{364}{4}$ = 91 km/hr $\therefore$ Speed of the first train = $\frac{6×91}{7}$ = 78 km/hr Hence, the correct answer is 78 km/hr.
