Study the given graph and answer the question that follows.

Number of male and female employees working in offices A, B, C and D of a company

Office	Percentage of employees who got a promotion
	Male	Female
A	42	44
B	40	60
C	45	55
D	64	30

 

The total number of female employees in offices B, C and D who got a promotion in what percentage more than the total number of male employees in offices A and C who did not get a promotion? (Correct to one decimal)

Given:

The number of female employees in office B = 250

The number of female employees in office C = 400

The number of female employees in office D = 550

The number of male employees in office A = 250

The number of male employees in office C = 500

Calculation:

The number of female employees in office B who got a promotion = 60% of 250 = 150

The number of female employees in office C who got a promotion = 55% of 400 = 220

The number of female employees in office D who got a promotion = 30% of 550 = 165

The number of male employees in office A who did not got a promotion = (100% - 42%) of 250 = 145

The number of male employees in office C who did not got a promotion = (100% - 45%) of 500 = 275

The total number of female employees in offices B, C and D who got a promotion = 150 + 220 + 165 = 535

The total number of male employees in offices A and C who did not get a promotion = 145 + 275 = 420

The required percentage = \(\frac{535-420}{420} \) ≈ 27.4%

∴ The total number of female employees in offices B, C and D who got a promotion is 27.4% more than the total number of male employees in offices A and C who did not get a promotion.
