If the Car A takes 25 hours to travel the distance then the speed of Car A is how much less than the...........

Quantitative Aptitude(IBPS CL) Case Studies

Direction: Study the given data carefully and answer the following question.

There are 3 cars A, B and C. They can travel some distance with different speed.

Car A: It travels some distance which is 33 1/3 more than the distance travelled by Car B.

Car B: It travels at speed of 50 km/hr for 7 1/2 hours.

Car C: It goes a distance of 400 km at 20% less speed than Car B.

If the Car A takes 25 hours to travel the distance, then the speed of Car A is how much less than the speed of Car B?

- Car B travels for 7.5 hours at a speed of 50 km/hr. This results in a distance of \(7.5 \times 50 = 375\) km.

- Car A travels 33 1/3 % more than Car B. So, it covers \(375 + \frac{33.33}{100} \times 375 = 500\) km.

- Car A takes 25 hours to travel 500 km. So, its speed is \(\frac{500}{25} = 20\) km/hr.

- The speed of Car B is 50 km/hr. The difference in speeds is \(50 - 20 = 30\) km/hr.

- The percentage difference is \(\left(\frac{30}{50}\right) \times 100 = 60\%\).

The correct answer is Option 2: 60%
