A. 760 km
B. 756 km
C. 740 km
D. None of these
Answer: Option B
Solution(By Examveda Team)
Ratio of speed of Bus and Train = 15 : 27 Let speed of the bus is 15X and Speed of the Train is 27X Car Covered 720 km in 9 hours. So, Speed of the Car = $$\frac{{720}}{9}$$ = 80 kmph Given, Speed of the bus is $$\frac{3}{4}$$ of Car, So speed of the Bus, = $$\frac{{80 \times 3}}{4}$$ = 60 kmph Thus, 15X = 60 X = 4 So, Speed of the train = 27X = 27 × 4 = 108 kmph. Hence, Train will cover distance in 7 hours, = 108 × 7= 756 km
