Abraham’s mathematics exam had 30 algebra questions and 50 geometry ques-
tions, each worth 1 mark. He got 70% of the algebra questions correct, and

his overall exam mark was 80%. How many geometry questions did he answer
correctly?

70% of 30 = 0.7*30 = 21

30 + 50 = 80

80% of 80 = 0.8*80 = 64

64 - 21 = 43
