Question

The number of males working in the IT department forms approximately what percent of the total number of males in the organisation?

• A. $5\%$
• B. $12\%$
• C. $21\%$
• D. $8\%$
• E. $18\%$

Answer 1

The correct option is B $12\%$

Total number of employees $=2400$
Number of male employees $=\frac{5}{8}\times 2400=1500$
Number of female employees $=\frac{3}{8}\times 2400=900$
Number of males in the HR department $=\frac{12\times 1500}{100}=180$
Number of females in the HR department $=\frac{11}{6}\times 180=330$
Number of females in the Accounts department $=\frac{24\times 900}{100}=216$
Number of males in this department $=(1500–180–185–630–330)=175$
Number of females in the IT department $=\frac{1}{9}\times 900=100$
Number of males $=285-100=185$
Number of males in the Production department $=\frac{42\times 1500}{100}=630$
Number of females $=\frac{10\times 630}{100}=63$
Number of males in the Marketing department
$=\frac{22\times 1500}{100}=330$
Number of females in the Marketing department $=(900–330–216–100–63)=191$

Required percentage $=\frac{185}{1500}\times 100=12\%$
