given that: Sue's tyre pressure gauge shows a reading which is 8% higher than the actual pressure

What is the actual pressure sue's gauge shows 39.42=?

if we calculate 8 % of total gauge that is 39.42 and subtract that percentage amount from total amount them we can get actual pressure

39.428%= 39.42 * 8/100

                =3.1526(reading higher than actual pressure)

now to find actual pressure than subtract higher reading from gauge shows reading:-

39.42-3.1526=36.26(actual pressure)
