Answer:
3 machine
Step-by-step explanation:
It is given that 6 machine each working at the same rate can complete the work in 12 days
We the has to complete in 8 days
Let we need x extra machine to complete the work in 8 days
So total number of machines =x+6
Now according to man work day equation [tex]M_1D_1=M_2D_2[/tex]
[tex]6\times 12=(x+6)\times 8[/tex]
[tex]8x+48=72[/tex]
[tex]8x=24[/tex]
x=3 machine
