Question

If 54% of a town’s population received the first two polio shots, but 10
percent of these persons did not receive the third, what percent of the
town took all three shots

Answer 1

Answer:

Here we know that the answer can't be higher than 54%, as this is the proportion who got the first two shots and a person can't get the third without getting the first two. So, from this 54%, the 10% didn't get the third shot. In other words, a tenth of this 54% didn't get the 3rd shot.
