Read the following information carefully and answer the questions bas...
From the bar graph,
Total number of employees in the company is 100%
So, (P/2 + 2 + 1.2P + 8 + P – 2 + 0.8P + 0.6P + 10) % = 100%
4.1P% + 18% = 100%
So value of P = 82/4.1 = 20%
Also,
(2Q + 5Q – 16 + 3.5Q – 2 + Q + 6 + 2.5Q) % = 100%
14Q% = 112%
So Q = 8%
Let total number of employees in a company and total number of male employees in a company is 100a and 100b respectively
Number of female employees in department A = 1280
So, 12% of 100a – 16% of 100b = 1280
12a – 16b = 1280
3a – 4b = 320…………. (1)
Number of female employees in company E = 3280
So, 22% of 100a – 20% of 100b = 3280
11a – 10b = 1640……………. (2)
On solving equation (1) and (2) we get
(11a x 2 – 3a x 5) = (1640 x 2 – 320 x 5)
7a = 1680
So, value of a = 240
On putting value of ‘a’ in equation (1), we get
Value of b = 100
So total employees in the company = 240 x 100 = 24000
So total male employees in the company = 100 x 100 = 10000
Now we can find the data for all departments of a company.
Total male employees in department C = 2600
Total female employees in department C = 1720
Now,
2600 x 25000 + 1720 x 20000 = 4320 x average salary of department C
10000 x (26 x 25 + 172 x 2) / 432 = average salary of department C
So, average salary of department C = Rs. 23009
Hence answer is option B
