  • Explanation:

    Ans. (67-70):

    Total number of employees = 4800

    So, total number of employees in company A

    =5/12×4800=2000

    Total number of employees in company B = 2800

    In company A.

    Number of male employees = 70/100×2000 = 1400

    ∴ Number of female employees = 2000-1400=600

    In company B,

    Number of male employees = 80/100×2800=2240

    Number of female employees = 2800-2240 = 560

    Comapny A

    Company B

    Male=1400 Male=2240

    Admin=70

    Operation=840

    Other Dept.=490

    Admin=196

    Operation=1456

    other Dept=588

    Female=600 Female=560

    Admin=144

    Operation=285

    Other Dept.=171

    Admin=49

    Operation=364

    Other Dept.=147

    Average number of males = 70+196/2=133

    Average number of females = 171+147/2 = 159

    ∴ Required difference = 159-133=26
