Question

There are 20 cars and motorcycles in a parking area .If there are 56 wheels altogether, how many cars are there?

Answer 1

Answer:

Step-by-step explanation:

Let number of cars in the parking area be X.

& number of bikes be Y.

Since the total number of vehicles are 20

We get X+Y=20……*

Since cars have four wheels and bikes have two wheels & given that total number of wheels are 56

We get 4X+2Y=56

That implies 2X+Y=28……**

From * & ** we get X=8 and Y=12.
