In our Singapore office there are 60% female employees. 50% of all the male employees

Ques - In our Singapore office there are 60% female employees. 50% of all the male employees are computer literate. If there are total 62% employees computer literate out of the total 1600 employees, then the no. of female employees who are computer literate :

(a) 690

(b) 672

(c) 960

(d) Can't determined 

Solution - 

Let,

Toal no. of employees = 1600

Toal no. of female employees = 60% of total employees

Toal no. of female employees = (60/100) × 1600

Toal no. of female employees = 960

Toal no. of male employees = 1600 - 960

Toal no. of male employees = 640

Total no. of computer literate male employees = 50% of 640 

= 320

Total no. of computer literate employees = 62% of total employees

= (62/100) × 1600

= 992

Total no. of computer literate female employees = total no. of computer literate - total no. of male computer literate 

= 992 - 320

= 672

Hence,

Total no. of computer literate female employees is 672.
