Answer:
15
Step-by-step explanation:
Let the number of cars be x and motorcycles be y.
x + y = 27 -------- (1)
Number of wheels in motorcycles = 2 and cars = 4.
There are 84 wheels altogether.
=> 4x + 2y = 84 ------ (2)
Solve 1 * 2 and 2, we get
=> 2x + 2y - 4x - 2y = 54 - 84
=> -2x = -30
=> x = 15
Place x = 15 in (2), we get
=> 4x + 2y = 84
=> 60 + 2y = 84
=> y = 12
Hence, the number of cars = 15
