Question

A teacher gave her class two tests. 50% of the class passed the first
test, but only 25% of the class passed both tests. What percentage of
those who passed the first test also passed the second test? %
25
100
50
12.5

Answer 1

Answer: 50

Step-by-step explanation:

50% of the class passed the first test, so that 25% that passed both test has to be part of the 50% that passed the first test. 25% that passed both is 50% of the 50% that passed the first test. Hopefully that makes sense.
