Answer 2

Answer:

15600 cars sold in previous years.

Step-by-step explanation:

let the car sold previous year =x

increase =12%

this year =17472

As per question,

$x + (x \times \frac{12}{100}) =17472$

$x + \frac{3x}{25} = 17472$

$\frac{28x}{25} = 17472$

$x = \frac{17472 \times 25}{28}$

$x = \frac{436800}{28}$

$x = 15600$

so 15600 cars sold in previous years
