Answer 2

7) 6 people took 9 hours to build a barn . Time taken by 6 people to build barn = 9 hours. Time taken by 12 people to build the same barn. Time taken by 12 people to build the same barn is 18 days.

8)The number is 141.

9) Irrespective of how the books are oriented the first page of everybook is page number 1 thus 1+1 = 2

10)They both weighs same because it is already mentioned that the iron and feather both are one pound. ... Here, it is asked about the pound, so one pound of iron is equal to one pound of feathers as the amount of feather is also one pound only

Hope this helps you
