Solutions:
(1 – 5):
Let total number of employees in H. R department be x and make table accordingly.  1. C) Number of employees in Sales dept. = Total number of employees – no of employees in other dept.
= (8000 – 2000 – 1000 – 2300 - 1200) = 1500
Number of male employees in Sales dept. = 1500 – 400 = 1100
2. E) We can’t determine the number of female employees in Finance department as we don’t know the number of males in this department or ratio between male and female in this department.
3. C) Ratio of the number of male employees in Operations to the number of female employees in HR = 200 : 800 = 1 : 4
4. C) 5. E) We can’t determine total number of female employees in the organizations because we don’t know the number of female employees in finance and marketing.
6. (a) required percentage = (14×80)/(21×72)×100=74% (approx)
7. (c) Packaged production of factory C = 8.5×16/100×75/100 lakh = 1.02 lakh
Total production of factory E = 8.5×15/100 = 1.275 lakh
Difference = 0.255 lakh = 25,500
8. (d) Packaged defective item production of factory B
=8.5×24/100×65/100×8/13 =0.816 lakh
Packaged non-defective item production of factory C
= 8.5×16/100×75/100×2/5=0.408 lakh.
Difference = 0.816 – 0.408 = 0.408 lakh = 40800
9. (d) Packaged non-defective item production of Factory A
= 8.5×21/100×72/100×5/12=0.5355 lakh
Packaged defective item production of factory E
= 8.5×15/100×70/100×4/7=0.51 lakh
Req.% = 0.5355/0.51×100 = 105%
10. (e) Req. % = (8-5)/5×100 = 60%
