In Jian's school, average score of two unit tests is considered the final score. First test is marked out of 40 and the second test out of 60. Jian scored

80% in the first test and in the second test he scored 90%. What is Jian's final score?



In the first test, out of 40 he scored 80%= 40*80/100=32 marks.
In the second test, out of 60 , he scored 90%= 60*90/100= 54 marks.

In two tests, total marks = 40+60=100 marks
He scored =32+54=86 marks.
Therefore, his final score= 86 marks out of 100 marks.
