Question

The average score Josie had in 6 subjects is 72 and her average score after 2 additional subjects were added is 74.25. If she scored 80 in the 7th subject, what was her score in the 8th subject correct to the nearest whole number?

Answer 1

Answer: 82

Explanation:

72 times 6 is equal to 432

6 plus 2 is 8

74.25 times 8 is equal to 594

If you minus 594 and 432 you get 162

162 is total marks for both subjects

162 minus 80 you get 82 which is the marks for the 8th subject
