Answer:

Their mass at the start was 400 kg.

Step-by-step explanation:

Given:

The tyres on a car during a grand prix race are reduced in mass by 3%. Their mass is 388 kg at the end of the race.

Now, to find the mass at the start.

<u>Let the mass at the start be $x$ .</u>

According to question:

$x - 3 \%ofx= 388$

⇒ $x-\frac{3}{100}\times x = 388$

⇒ $x-0.03x =388$

⇒ $0.97x=388$

<em>Dividing both sides by 0.97 we get:</em>

⇒ $x=400$

Therefore, their mass at the start was 400 kg.
