Answer:
Cars - 5
Bikes - 13
Step-by-step explanation:
Let the number of cars be x.
⇒ Number of bikes = (18 - x)
∵ There are 2 tyres in each bike while 4 in each car,
So, total tyres = 4(x)+ 2(18-x) = 46
⇒ 4x + 36 - 2x = 46
⇒ 2x = 46 - 36
⇒ 2x = 10
⇒ x = 5
⇒ Number of cars = x = 5
Number of bikes = (18-x) = 18 - 5 = 13
