9 people can build a wall in 8 days, how many people would build it in 12 days?
Answers
Answer:
Step-by-step explanation:
Days required to build the wall = 15×12 = 180
Days required by 1/4 th efficient people to build the wall =4×180 = 720
Days required by 1/4 th efficient 9 people to build the wall = 720/9 = 80 days
Days required by 1/4 th efficient 9 people to build 3/8 th of the wall = 80×3/8 = 30 days.
Answer:
6 people will be required to build the wall in 12 days
Step-by-step explanation:
Here it is given that 9 people can build a wall in 8 days
We have to find the number of people required to build it in 12 days
Let us assume the number of people required to be x
We will use inverse proportion
days required by 9 people = 8 days
days required by x people = 12
12x = 9 × 8
12x = 72
x = 72/12
x = 6
