Assuming that in the base year 1994 cars stolen were 100, the number of stolen cars in 1997 and 1998 are respectively 88 and 80.6. Then, the percent decrease is computed as
(80.6-88)/88*100 = -8.4%. Answer C

Why we did not say, 19.4-12=7.4% ?

I totally agree. The answer provided by ilcreatore was made having in mind the official solution provided by the author.

However, for me the answer C is elaborated in such way to make the question difficult.

Here we do have a simple % change. The universal rule for %change says that you make the following fraction

Starting value - the decreasing value / starting value = 7.4 %

Tha answer should be A.

Regards

IlCreatore did exactly that and got result C, not A.
