Question

in how many days b alone can do the same work?
​

Answer 1

Answer:

the answer should be 48 hours

Step-by-step explanation:

but there is no options saying that . here is the explanation .

let w be the total work units .

rates of output are A = u units/ day B=v units per day .

W/(u+v)=16

W/u=14

16+(u+v)=24u

8u=16v

v=0.5u

no. of hours taken by b alone =W/v=2w/

=2*24=48hours
