Question

Sue's tyre pressure gauge show a reading which is 8% higher than the actual pressure. What is the actual pressure when Sue's gauge shows 39.42?

Answer 1

The actual pressure is =36.5

Step-by-step explanation:

Given,

Sue's tyre presser gauge show a reading 8% higher than the actual pressure.

Sue's gauge shows 39.42.

Let the actual pressure be x.

According to problem

      $x\times\frac{108}{100} =39.42$   [If 8% increasing  of a no ⇒ The number becomes =                      $(\frac{100+8}{100})$of the number

⇔   $x = \frac{39.42\times100}{100}$

⇔  $x=36.5$

So , the actual pressure is =36.5
