The number of blue cars has to be divisible
by both 2 and 3, so the smallest number of
blue cars is +6+
-------------------------
For every 2 blue cars there are 5 silver cars
+3%2A5+=+15+ is smallest number of silver cars
-----------------------------
There are 2 white cars for every 3 blue cars
+2%2A2+=+4+ smallest number of white cars
+6+%2B+15+%2B+4+=+25+
