That would be B, C and E.
A and D could be a rhombus.
Let x be the total number of students.
The total of red + blue = x/4 + x/8
The remaining will be : x - x/4 -x/8
But we know the green at 3/5 of the remaining, so the green = 3/5(x - x/4 -x/8)
We also know that 3/5(x - x/4 -x/8) = 15
Solve this equation: and you will find x = 40 (number of students)
The answer is
1.98x10^-3
I hope that’s correct.
You can check what I did.
I just wrote out the equation and then plugged them into the calculator.
Between -2&-1 is the answer
