Question

Alice tyre pressure gauge shows a reading which is 8% lower than actual pressure

what is the actual pressure of Alices tires when the gauge shows 33.58

Answer 1

30.8936

Explanation:

Pressure guage reading is 8% lower than tbe actual pressure.

Therefore, for a tyre with guage pressure, 33.58 ;

The actual pressure of tyre would be :

Guage pressure - 8% of guage pressure

33.58 - (0.08 * 33.58)

33.58 - 2.6864

= 30.8936

Actual pressure = 30.8936
