Study the given pie-chart and answer the question that follows.

The pie-chart represents the consumption of fuel (in million litres) by various modes of transport of a country X in the year 2015. The total consumption of fuel by various modes of transport of the country is 800 million litres. (The data shown here is only for mathematical exercise. They do not represent the actual figures of the country.)

The fuel consumed by light vehicles is approximately what percentage of the combined consumption of fuel for aviation and water ways?

52

Fuel consumed by light vehicles = 70º

Combined consumption of fuel for aviation and water ways = 90º + 45º = 135º

Required percentage = \(\frac{70º }{135º}\) × 100

= 51.85%

= 52%  ( approx )
