Question

ali's tyre pressure gauge shows a reading witch is 8 % lower than the actual pressure when the gauge shows 33.58

Answer 1

Answer:

the actual pressure is 31.09

Complete question:

What is the actual pressure when Ali's gauge shows 33.58

Step-by-step explanation:

Given,

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

Ali's gauge shows 33.58.

Let the actual pressure be x.

According to problem,

 $x\times\frac{108}{100} =33.58$ { [If 8% increasing  of a no ⇒ The number becomes =                      $(\frac{100+8}{100})$of the number}

x= $\frac{33.58\times100}{108}$

x=31.09

Therefore, the actual pressure is 31.09
