In an office, 70% of the total number of employees are females. 80% of the total number of employees, including 85 males, got promotion.If there are 105 female employees, then what percentage of female employees got promotion?
Answer & explanation
Correct answer: option 1
70% of total employees = 105 (given)
Total employees = 105 × \(\frac{10}{7}\) = 150
Number of males employees = 150 – 105 = 45
Number of all promoted employees = 150 × \(\frac{80}{100}\) = 120
Number of promoted males employees = 35
Number of promoted females employees = 120 – 35 = 85
% of promoted females employees = \(\frac{85}{105}\) × 100 = 80.95%
