One day, each driver entering a car park paid exactly £1.50.

The machine only accepts £1 coins and 50 p coins.

Here is what was put into the machine that day.

Number of £1 coins = 136

Number of 50p coins = 208

On that day, what percentage of drivers paid with three 50p coins?

Roughly 17% of people would have paid with 3 50p coins. That's what I came up with.
