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 ![M_1D_1=M_2D_2](https://tex.z-dn.net/?f=M_1D_1%3DM_2D_2)
![6\times 12=(x+6)\times 8](https://tex.z-dn.net/?f=6%5Ctimes%2012%3D%28x%2B6%29%5Ctimes%208)
![8x+48=72](https://tex.z-dn.net/?f=8x%2B48%3D72)
![8x=24](https://tex.z-dn.net/?f=8x%3D24)
x=3 machine
22 because you take the smallest and largest number and subtract them so you do 81-59=22
5x7-3x8+11
35-24+11
11+11
The answer is 22
