Question
In a department 30% of the employees are females. 40% of
the male employees know English. The total number of employees who know English is 46%. Find the percentage of females’ employees who know English.Solution
Let the total number of people in the department = 100x Given, females = 30% = (30x), males = 70% = (70x) 40% of males know English = 40% of 70x = 28x Total number of employees who know English = 46% of 100x = 46x Total females who know English = 46x - 28x = 18x Percentage of females who know English = (18x/30x) × 100 = 60%
