Worker A can complete a job in 20 hours and worker B can complete a job in 25 hours if both workers work together how long will it take them to complete the job?
The way to calculate this is to figure out what fraction each does in an hour (1/20 of the job, vs. 1/25 of the job). Add the fractions together to see how much they do together in an hour, then take the reciprocal to find out how many hours it takes them.
Two people are painting a fence one takes 3 hours to complete the job and one takes 6 hours to complete the same job how long would it take for both to complete the same job -?

If it takes 10 electricians to get the job done in 6 hours how many electrician will it take to complete the job in 4 hours?
It should take 15 electricians provided that two unlikely conditions are satisfied:all electricians work at exactly the same rate, andthe job contains no parts which are time-dependent. For example, if an instalment must be tested for 5 hours, then even infinitely many electricians will not do the job in 4 hours.

How can you say that time is money?
Typically, jobs are based on either a per-hour rate or a flat fee (salary). When using the per-hour basis, the longer a job takes, the more money is earned. Alternately, a flat-fee or salary based job gives one price no matter the length of time a job may take. Therefore, the longer a job takes, the less money one would make. For example, if a job is quoted at $100 and it takes 10 hours to complete, the average earnings would equal $10 per hour, subsequently, if the time to complete the job were only 2 hours, the earnings would be $50 per hour.

My somewhat educated guess would be two hours. The person who could complete the job in 3 hours could complete 2/3 of the job in two hours. The person that complete the job in 6 hours could complete 1/3 of the job in two hours. 2/3 + 1/3 = 1.
