Question

There were 13,531 new products introduced last year. If 87% of the products introduced last year failed to reach their business objectives, find the number of products that were successful.

Answer 1

I'm assuming that since 87% failed, that would the remaining 13% was a success.  If that assumption is correct, than we simply have to take:

.13 * 13531 = 1759.03 products were successful.
