Question
In a group of 104 employees, the
ratio of male to female employees is 6:7. The average wage of a male employee is Rs. 45, and the total wage of all employees combined is Rs. 4,120. What is the average wage of a female employee?Solution
ATQ,
Number of male employees = 104 × (6/13) = 48 Number of female employees = 104 – 48 = 56 Total wage of all male employees = 48 × 45 = Rs. 2,160 So, total wage of all female employees = 4120 – 2160 = Rs. 1,960 So, average wage of a female employees = 1960 ÷ 56 = Rs. 35
