If 200 ltr of juice is filled in bottles by 50 workers in 6 days, then 50 ltr of juice can be filled in bottles by 25 workers in how many days?
Here less workers, required more days, so it is indirect proportion. The multiplying factor is 50/25.
Less work done required less days to fill the juice, so it is in direct proportion. The multiplying factor is 50/200.
x=6×(50/25)×(50/200)=3
Therefore, 3 days have been required.
