Hey guys, I've a got a questions which is kinda confusing...
A company orders a number of bottles from a factory.
The 8 machines in the factory could make all the bottles in 5 days.
All the machines work at the same rate.
For 2 days, only 4 machines are used to make the bottles.
From the 3rd day, all 8 machines are used to make the bottles.
Work out the total number of days taken to make all the bottles.
Ok... so far I've worked out that it would take 1 machine 40 days to make all the bottles as 8 * 5 = 40
so it would take 4 machines 10 days. Then what?
My friend told me that he worked it out to be 6 days and that he got it correct but his explanation was messed up!
