Question

A bike gives a mileage of 70 km/L. How much petrol is required to travel a distance of 350 km?

• A. 5 L
• B. 3 L
• C. 1 L
• D. 10 L

Answer 1

The correct option is A 5 L

Items in the ratio	Numbers in the ratio	Values of items used	Multiplier
Distance	70	350	5
Volume	1	5	5

Here, ratio of distance covered to volume of petrol is 70:1.

We need to find the volume of petrol required to cover 350 km.

$\Rightarrow$ 70:1 = 350:Volume of petrol (since both are equivalent ratios)
$\Rightarrow$ 70:1 = 70 $\times$ 5:Volume of petrol
$\Rightarrow$ Volume of petrol = 1 $\times$ 5
= 5 L

Therefore, to cover 350 km, we would need 5 L of petrol.
