Question 628273: If 5 machines complete a certain task in 12 days, how many machines are needed to finish the same task in 10 days? Found 2 solutions by bondc, hibiskus:Answer by bondc(3) (Show Source):
You can put this solution on YOUR website! 5 machines = x machines
12 days 10 days
50 = 12x
x = 25/6 or 4.11111 machines
Since machines cannot be bought this way, the answer is still 5.
You can put this solution on YOUR website! If 12 then 5. If 10 then how many?
12 -> 5
10 -> x
now by forming the rate we have this
12/10=5/x
and it's not direct proportion then we have
12/10=x/5 after multiplication side to side by 10 we have
12=2*x
x=6
there are 6 machines
have a nice day
