hope it helps . please mark me as BRAINLIEST . thank you

Step-by-step explanation:

So according to the question ~

We have following details,

Total no. of Vehicles = 21

Total no. of Wheels = 60

Now, lets suppose the total no of cars and bikes present in the parking ground be x and y respectively.

Therefore,

x + y = 21 … (1) [Given]

& 4 x + 2y = 60 … (2) [ Because there are 4 wheels in 1 car & 2 in bikes so 4 × x and 2 × y]

By solving the equations we get x= 9 & y=12

Conclusion : There were in total 9 cars and 12 bikes present in the parking ground.
