Answer 1

Answer:

8 men

Step-by-step explanation:

First you have to calculate units of work

W= Men×Days×Hours

W= 12×10×8= 960 units

Now to complete these 960 units in 8 days, while working 15 hours a day, the no. of men required will be= 960÷(15×8)= 8 Men

Answer 2

Answer:

Total time to finish the work is10×8hours =80hours

80 hours required for 12 men

1 hour required for 12×80 men

15×8hours required for 12×80/15×8men

=8men

8 men will require to finish the work
