Answer:

let working speed of first person=2x

working of second person=2x ------ given

working of third person= X -------acc. to q

2x + 2x + X = 5x

it means 3 people do certain work in 12 days

2x+2x+X=12 days

5x = 12

X=12/5

X= 2.4 days

since, trird person do its one day work in 2.4 days

therefore work of 12 days = 12*2.4

= 28.8 days
