aishwarya finished 1/5th of job on Monday, 2/5th on Tuesday and 3/10th on Wednesday, what part of the job was finished on these three days, what part of the work is left?
with step by step explanation​

Answer 1

Answer:

A can do 1/3 of work in 20 days

A can do 100% work in =20*3=60 days

So in one day A can complete 1/60 of work.

B can do 1/2 of work in 20 days.

B can do full work in 20*2= 40 days

So in one day B can complete 1/40 of work.

If A & B work together for one day, part of work can be complete as

-> 1/A+1/B=1/60+1/40 =(2+3)/120 =5/120 =1/24

So in one day, A & B together can complete 1/24 of work.

If A & B work together, time required to complete work is 24 days.
