Total number of worker at Factory at A = 1500

Percentage of Men workers = 45

Total number of Men workers = 45/100 × 1500 = 675

Salary of a Man worker = 6000

Total amount given to Men workers = 675 × 6000 = 4050000

Percentage of Women workers = 35

Total number of Women workers = 35/100 × 1500 = 525

Salary of a Woman worker = 4000

Total amount given to Women workers = 525 × 4000 = 2100000

Ratio of total amount given to men to the total amount given to women =

4050000 : 2100000

= 27:14

Total number of worker at factory B = 1200

Percentage of Women workers = 40%

Number of Women workers = 40/100×1200 = 480

300 Men workers were absent on a particular day.

Total number of workers on that particular day = 1200 – 300 = 900

Percentage of Women workers on that particular day =

=  480/900 × 100 = 53⅓%

Percentage of Child workers at Factory C = 15%

Number of Child workers at Factory C = 96

Total number of Workers at Factory C = 96/15 × 100 = 640

Number of Men workers at Factory C =  65/100 × 640

= 416 workers

Total number of workers at Factory A = 1500

Percentage of Women workers at Factory A = 35%

Number of Women workers at Factory A = 35/100 × 1500 = 525

Total number of workers at Factory D = 1800

Percentage of Child workers at Factory D = 25%

Number of Child workers at Factory D =  25/100 × 1800 = 450

Ratio of number of women workers at Factory A to number of Child workers at Factory D = 525 : 450

= 7 : 6

Total number of worker at Factory B = 1200

Percentage of Men worker = 50%

Number of Men worker = 600

Percentage of Women worker = 40%

Number of Women worker = 480

Percentage of Child worker = 10%

Number of Child worker = 120

Man is three times more efficient than a Woman and a Woman is two times more efficient than a Child.

Woman produces 4 articles per day.

So, Men will produce 12 articles per day and A Child will produce 2 articles/day.

So,total number of Articles produced at Factory B in one day =

= 600 × 12 + 480 × 4 + 120 × 2

= 7200 + 1920 + 240

= 9360 articles

Profit on 1 article = 6 paise

Profit on 9360 articles = 9360 × 6 = 56160 paise or 561.60 ₹

Hence, the amount that the owner of Factory B earns in one day = 561.60 ₹
