What is the formula for working together problems?
To solve a work word problem, multiply the hourly rate of the two people working together by the time spent working to get the total amount of time spent on the job. Knowledge of solving systems of equations is necessary to solve these types of problems.
How do you calculate work together?
The conclusion of the concept is if a person does a work in ‘r’ days, then in 1 day- 1/rth of the work is done and if 1/sth of the work is done in 1 day, then the work will be finished in ‘s’ days. Thus working together both can finish 1/h (1/r + 1/s = 1/h) work in 1 day & this complete the task in ‘h’ hours.

How do men solve problems at work?
Solution 1:
- As 12 men complete the job in 24 days, the work amount is 12×24=288 mandays.
- For this group of men the total work amount is 288 man days.
- Thus if 12 men and 12 women work together for a day, it is equivalent to (12+24)=36 men working on the job for 1 day.
