Answer 1

Answer:

Step-by-step explanation:

heya!!!!!!!!!!!!

here is ur answer

work done by 5 machines per day = 1/16

work done by 5 machines per hour =  1/16×9

work done by 1  machines per day per hour =  1/16×9×5

let 'x' be the days taken by 8 machines which is operated 10 hours each day.

       Thus,

                     work done by 8 machines working 10 hours each day for' x' days' =8×10×x

                            thus,

                                           [1/16×9×5]  × [8×10×x] = 1

                                           ⇒ x = 9 days
