Question

A car travels 50 km with 2 litres of fuel. What distance will the car travel if the fuel tank has 4 litres of fuel?

• A. 75 km
• B. 80 km
• C. 100 km
• D. 200 km

Answer 1

The correct option is C 100 km

Ratio of the distance travelled by car to fuel consumed = 50 : 2 = 25 : 1

In this ratio numerator represents distance in km and denominator represents fuel in litres.

So, the car travels 25 km per litre.
Now the denominator is given as 4 litres that is $1\times 4$.
So, the numerator becomes $25\times 4=100$

Hence, the ratio = 100 : 4
Thus, with 4 litres of fuel, the car can cover 100 km of distance.
