Question

Out of 250 million cars on the road in US, about 3% are diesel. What percentage are not diesel?

Answer 1

Answer:

100% -3 %so the answer is 97%

Answer 2

Given,

Total number of cars on the road in US = 250 million

Percentage of cars running on diesel = 3%

To find,

Percentage of cars not running on diesel.

Solution,

We can simply solve this mathematical problem using the following process:

Mathematically,

For a certain event, the sum of the percentage of occurrence of all its alternatives is equal to 100.{Statement-1}

Now, according to the question;

The event of concern is the fuel on which 250 million cars on the road of the US run.

So, its two alternatives are either a car runs on diesel or else it falls in the category of not running on diesel.

Now, the percentage of cars running on diesel = 3%

So, according to statement-1;

The percentage of cars not running on diesel

= 100% - (percentage of cars running on diesel)

= 100% - 3%

= 97%

Hence, the percentage of cars on the road in the US that are not running on diesel is equal to 97%.
