Question
In a factory, there are 180
workers comprising both males and females. If 25 male workers are replaced with 25 female workers, the ratio of males to females in the factory becomes 5:6. Determine the initial number of male workers in the factory.Solution
ATQ,
Let the number of males in the factory initially be x. Number of females in the factory initially = 180 − x. After replacing 25 males with 25 females, the number of males = x − 25 and the number of females = 180 − x + 25. ATQ, 
Simplifying: 6(x−25) = 5(205−x) 6x − 150 = 1025 − 5x 11x = 1175 x = 107 Number of males in the factory initially = 107.
