The percentage score of the student can be written as the ratio
.
However,
.
Equating the two:
.
Cross-multiply (that is: multiple both sides by , the product of the two denominators) to get
.
.
In other words, there are 80 marks in total.
The answer is x=6. 9x-6=3x+30
9x-3x-6=3x-3x+30
6x-6=0 +30
6x-6 + 6= 0 + 30 +6
6x=36
6x/6=36/6
x=6
80.337 is the answer
Answer:
Simplifying
x = 5
