Problema Solution
In a class of 74 students, the number of females is one fewer than twice the number of males. How many females and how many males are there in the class?
Answer provided by our tutors
let 'x' represent the number of males students, then '2x-1' represents the number of female students:
74 = x + 2x-1
75 = 3x
x = 75/3 = 25
2*25 - 1 = 49
there are 25 female students and 49 male students
