Jack and Jill campared their results on their last exam.Jack had 40 questions correct and Jill had 50 questions correct.There were 32 questions that they both got correct and 6 questions they both got wrong.How many questions are on the test?

Answer 1

out of n, n-6 were gotten right
so let's find n-6

Jack alone got 40 -32 = 8
Jill alone got 50-32 = 18

so in total alone they got 26
plus they got 32 together
26 + 32 = 58 right total

plus the 6 wrong = 64
