Fred is completing some exams. He is trying to work out how many marks he needs to score on the final paper to pass the module.
The examination is made up of three papers.
Paper 1 is marked out of 60.
Paper 2 is marked out of 40.
Paper 3 is marked out of 100.
The three marks are added together to form the total mark out of 200.
Fred scored 65% on Paper 1 and 70% on Paper 2.
Work out the mark Fred needs to get on Paper 3 to achieve 64% of the total marks and pass the module.
Answer:
First find the number of marks Fred scored on Paper 1 and Paper 2
Paper 1:
Fred scored 65% of 60 so multiply 60 by the percentage multiplier of 0.65 to find the number of marks at 39
Paper 2:
Fred scored 70% of 40 so multiply 40 by the percentage multiplier of 0.7 to find the number of marks at 28
Therefore, Fred has a total of 67 marks already
Then find out what 64% of 200 is by multiplying 200 by the percentage multiplier of 0.64 to get 128
Therefore, Fred needs 61 marks on paper 3 to get 64% in total.
