Problem Solving (PS) | Re: Jack and Jill working separately complete a work in 8 days and 12 days

Jack : Jill
Days: 8 : 12 LCM(8,12) = 24 So let 24 be the total work.
Rate: 3 : 2 24 total work divided by days to finish work gives rate.

Now, In 1 day Jack can finish 3 parts of total work and Jill can finish 2 parts of total work.

So, If Jill starts the work and Jack follows him next day then in 2 days they finish 5 parts of work.

Our total work is 24. So 24/5=4(only proper quotient). Hence in 4X2= 8days they finish 20 parts of work.

Remaining part = 4. Again
