28

Explanation:

5 :7 is the ratio between bicycles and buses, not their actual number.

Their actual number will be a multiple of these numbers.

What I mean is that the number will be 5x bicycles and 7x buses, where x is any whole number.

Then, the total number of vehicles is 5x + 7x = 12x, which in this case is 48.

So,
12x = 48

Dividing both sides by 12,

x = 48/12

Therefore, x = 4.

Now, the number of buses is 7x, 7xx4 = 28.
