Answer:
The time required by 9 people to paint 7 walls is 49 minutes
Step-by-step explanation:
Given as :
The number of people (p1) = 7
The work done by them (w1) = 4
The time taken (T1) = 36 minutes
Again :
The number of people (p2) = 9
The work done by them (w2) = 7
Let the time Time taken (T2) = T2
So, we know as :
= Constant
SO, =
Or, =
Or, =
Or , = T2
∴ T2 = 49 minutes
Hence The time required by 9 people to paint 7 walls is 49 minutesAnswer
