In a parking lot, there were 90 vehicles which are cabs, tricycles, and bicycles. When Raul counted the wheels, there were 210 in all. How many of each kind of vehicle were there?

Sagot :

There are 12 cabs, 12 tricycles and 66 bicycles.
A cab has a 4 wheels. 4 multiply by 12 is equal to 42 wheels.

A tricycle has a 3 wheels. 3 multiply by 12 is equal to 36 wheels.

A bicycle has a 2 wheel. 2 multiply by 66 is equal to 132 wheels.
So, there for 12+12+66 is equal to 90 where in 90 is the sum of all vehicles.

And 42 + 36 + 132 is equal to 210 where in it is the total of the wheels Raul counted.
