(2)​

Answer 1

to paint 4 buildings it will take 10 labourers  3 days.therefore it will take 6 days.

Answer 2

Step-by-step explanation:

Number of days taken by 5 labours to paint 2 identical buildings = 3

Number of days taken by 1 labour to paint 2 identical buildings = 3×5 = 15

Number of days taken by 1 labour to paint 1 building = 15/2

Number of days taken by 1 labour to paint 8 identical buildings = 15×8/2 = 60

Number of days taken by 10 labour to paint 8 identical buildings = 60/10 = 6
