Explanation:
20 men can do 1 W in 36 days
=> 20 men can do 1/36 W in 1 day
=> 10 men can do 1/72 W in 1 day.
30 girls can do 1W in 36 days
=> 30 girls can do 1/36 W in 1 day
=> 12 girls can do 1/90 W in 1 day.
Together 10 men and 12 girls can do 1/72 + 1/90 W in 1 day
= 9/360 = 1/40 W in 1 day.
Therefore they need 40 days to do the piece of work.

"Recycle" would not be one of the famous creative "Rs". This is mostly because the point of this process is to find new ideas by building on small ideas, not to use old ideas over and over again.
The Industrial Revolution brought with itself a new dynamic between employer and employee. The main change of the revolution in this dynamic was the introduction of the worker's safety, as one of the main requirements that every business and workplace should have in order to operate. The public safety regulations exist in order to protect the workers from different hazards that the job can bring. It also sets some boundaries and rules for the employer to consider and follow, in order to protect the safety of the employees. Employers need to evaluate what things can harm the employees and implement the required protections so that no accidents occur. Workers are also trained in terms of safety in the workplace, so that they can identify any risk and avoid it. At every work place there should be first aid's facilities and medical support, in the events of an accident. Every employee has to be insured at his/her work in case they get sick or injured while working. Public safety regulations exist to protect and benefit the workers in their workplace.
