Question 17
In a company, the average salary of the boys is Rs. 50000. The average salary of all the employees is Rs. 48000. There are 80 boys in the company and the average salary of the girl is Rs. 40000. What is the number of girls working in the company?
Solution
Let girls be x
Total employees will be 80+x
now total value of money will be same :
i.e Average of 1employee (Number of employees ) will be equal to (Average of boys)* Number of boys +(Average of girls)*Number of girls
we get 48000(80+x) = 50,000(80)+40,000(x)
48(80+x) = 50(80) +40x
we get 8x =160
x=20
