Question

10man complete 1 wall in 8 days how many man complete wall in half day

Answer 1

Answer:

Step-by-step explanation:

Number of men work inversely proportion to number of days to finish

 

x= number of men

y=number of day

 

y=k/x

 

8=k/10

80=k

equation is

y =80/x

 

constant =k= 80

 

so when want to finish work in 1/2 day how may men required?

 

means when y= 1/2  what is value of x

 

y=80/x

 

1/2 = 80/x

by cross multiplication

x =160

so 160 men are required to finish work in 1/2 day

 

So number of men added is 160-10=150
