Answer:

16.67% ( approx )

Step-by-step explanation:

Given,

Total number of serviced car = 72,

Out of these, the number of cars serviced that needed mufflers = 12,

Thus, the percent of cars serviced that needed mufflers

=\frac{\text{Cars that needed mufflers}}{\text{total serviced cars}}\times 100

=\frac{12}{72}\times 100

=\frac{1200}{72}

\approx 16.67\%
