Given:
A rectangular piece of cloth (dimensions):
L = length of the rectangle
W = width of the rectangle
The area of the rectangle is:
A = L x W
If the cloth is cut along the diagonal, the area of one sail will be half the area of the rectangle:
A (one sail) = 1/2 (L x W) <span />
The answer is obviously not A and B so that leaves us with only C or D and the one that id the best choice would have to be C because it gives good information about how it is used and where it would be installed
Hope this helped : )
First case:
average of test score =70
number of students =p
total score of 'p' students = ( average of test score)*( number of students)
total score of 'p' students =70p
Second case:
average of test score =92
number of students =n
total score of 'n' students = ( average of test score)*( number of students)
total score of 'n' students =92n
total number of students = p+n
total average score =86
so, total score =86(p+n)
total score = total score of 'p' students +total score of 'n' students

now, we can simplify it



now, we can find p/n
