Question

A and B can do a work in 18 days . A alone can do the same work in 27 days . in how many days can B alone do the same work​

Answer 1

Answer:

A+B can do work in 18 days

A alone can do in 27 days

we do not have what amount of work we have

so assume then total work is lcm of 18 and 27 i.e 54

if total work is 54 then in one day A+B do 3 unit of work

and alone A do 2 unit of work

so it is clear that B do 1 unit of work alone

total work is 54

B=54/1

B do that work in 54 days
