Answer is B.
hope it helps
I can try but which problems?
Answer:
Is the w2, w(2) or
![{w}^{2}](https://tex.z-dn.net/?f=%20%7Bw%7D%5E%7B2%7D%20)
?
If it's w(2) the answer is -4--8+1=-4+8+1=5
if it's w^2 then the answer would be 4--8+1=4+8+1=13
Let, the number of student = x
Fraction of boys = 1 - 2/5 = 3/5
So, it would be: x * 3/5 = 1482
x = 1482*5 / 3
x = 7410/3
x = 2470
Thus, There are total 2470 students
Hope this helps!
