Worker A finishes a project on his own in 12 days and worker B does the same in 16 days.
Worker A does 1/12 of the project in one day and worker B does 1/16 of the project in one day. When working together, they do
After 3 days they have completed:
parts of the project, this means it still remains:
parts of the project and it is done by B alone. Since B does per day, he now takes
days to complete the project.
Worker B needs 9 days to finish the rest of the work
Answer:
Square root of 4 is 2
so 1+=4
frac{[1+sqrt{2x-1]}^2 }{4}=3
so 1+sqrt{2x-1]}^2=12
so 1+sqrt{2x-1}=V12
sqrt{2x-1}=V12-1
2x-1=(V12-1)^2=12-2V12+1=13-2V12
2x=13+1-2V12
2x=14-2V12
x=7-V12
x=7-2V3
