Question

John missed 4 problems on a test but did 75% of them correctly. How many problems

were there in the test?

Answer 1

Answer: 16 problems

Explanation:

First find out how many John got wrong. 100%-75%=25%. Then do cross multiplication: 4*100=25x; 400=25x. Divide 25 on both sides and... BOOM! you get 16 problems.

Answer 2

16

Explanation:

he missed 25%

if 4 = 25% then 16 questions total

4*4=16 and 25% * 4 = 100%
