how to i solve this problem asked previously unsatisfied with ans. Jack and Jill copared results on math test. Jack had 40 correct ans & Jill had 50 correct ans. There were 32 questions they both had correct and 6 they both had wrong. How do I determine how many questions were on the test?
total number of questions

Consider this argument:
(40-32) + (50-32) + 6 + 32 = y (y being the number of questions) (their results must minus the 32 first in order to get the number of questions they got correct, but not together)
8 + 18 + 6 + 32 = y
y = 64 questions
