Answer:
7 people, 7 walls, 48 minutes
Each person paints 1 wall in 48 minutes
20 persons, 20 walls
Each person can paint 1 wall in 48 minutes so it will take 48 minutes.
X+3=61
x=61-3=58
58+37=95
180-95=85
so x=58 and y=85
It is multiplying by 20. Therefor output for 10 would be 200. the missing input would be 8 making the output 160
Im not 100% that thats correct but im pretty sure it is.
