Directions: Study the given information carefully to answer the questions.

Ram goes to a hill station by car. While going upwards (uphill) the consumption of petrol was increased by 25% of the normal consumption of petrol but while going downwards (downhill) the consumption of petrol was decreased by 50% of the normal consumption of petrol. He goes from the point A to the point B. The total distance between point A and point B is 525 km in which the total distance travelled by him uphill is 2.5 times of the total distance travelled by him downhill and the total distance travelled by him on the plane surface is 140 km. While coming back from the point B to point A, he saves 15 litres of petrol and the consumption of petrol is normal on plane surface.

What is the difference between the mileage of car on downhill and that on uphill?

1 litres per 33 kilometres

1 litres per 22 kilometres

1 litres per 11 kilometres

1 litres per 9 kilometres

1 litres per 10 kilometres

Explanation:

Following the explanation, we get
The required difference = 5x – 2x = 3x = 3/33 = 1/11 litres per kilometres = 1 litres per 11 kilometres
Hence, option C is correct.
