Great! (Question: 153062.0 )

damn this was a tricky one!

Question:
The ratio between the male and female existing employees in an organization is 7 : 3. The ratio between the male and female in new recruitment of 240 employees is 5 : 7. What will be new ratio between male and female employees after the recruits join the organization?
Options:
A) 6:5
B) 5:4
C) 3 : 2        
D) Can’t be determined
Solution:

Let the numbers of existing male and female employees in an organization be 7x and 3x .

Total number of new recruits = 240

 Ratio of male and female of new recruits 5 : 7

Number of male new recruits

=  \(\frac{5}{12}\) × 240 = 100

Number of female new recruits = 240 – 100 = 140

ratio between male and female employees after the recruits join the organization

=  \(\frac{7x+100}{3x+140}\)

So, option (4) is best choice.
