Here's what we know:192 * 40/90 * 3/16There are 192 people, of them there 40/90 of the populace as bowlers, and of that, 3/16 are ball owners. Let's start simplifying:40 and 90 share a 10:192 * 4/9 * 3/16 4 and 16 share a 4:192 * 1/9 * 3/4 9 and 3 share a 3:192 * 1/3 * 1/4 192 and 3 share a 3:64 * 1/1 * 1/464/416 So there will be about 16 people who own a bowling ball of their own.
