A factory has 500 workers, 15% of whom are women. If 50 additional workers are to be hired and all present workers remain. How many of additional workers must be women in order to raise the percent of women employees to 20%.
A. 3
B. 10
C. 25
D. 30
E. 35
OA E
I have a doubt in this question
I used the allegation of mixtures
The proportion needed of each ingredient is equal to the distance between the OTHER two percentages.
Let the % of women in new workers be x
so ration of old to new workers can be written as
(x-20)/(20-15) = 500/50 or x = 30%
30% of 50 = 15. Please help me find my mistake
