Answer 1

Hi mate!

Answer:-

We will apply unitary method.

Time required by 12 workers= 8hrs.

Time required by 1 worker= 8/12 hrs.

Thus,

Time taken by 10 workers= Time taken by 1 worker x 10

                                           = 8/12 x 10

                                            =6.66 hrs.
