Question

A student missed 52 problems on a physics test and received a grade of 10%. If all the problems were of equal value, how many problems were on the test? Round your answer to the nearest integer.

Answer 1

0.90x = 52  ... 90% wrong

 

Solve for x.

 

A well designed question of this type would have answer x = integer; this one does not.
