Mo’s tyre pressure gauge shows a reading which is 12% higher than the actual pressure. What is the actual pressure when Mo’s gauge shows 38.64?

Using proportions, it is found that the actual pressure is of 34.5.

The rule of three is:

38.64 - 1.12

x - 1

Applying cross multiplication:

The actual pressure is of 34.5.

34.5

Step-by-step explanation:

Given that :

112% = 38.64.

We need to calculate 100%

DO this by finding 1% then multiply that by 100.

112% = 38.64

1% = 38.64/112 =  0.345

100% = 34.5

Hope this helps.
