Answer :
It will take 21.53 hours for 8 workers and 5 bandits to lay 1400 bricks.
Given that one worker can lay 10 bricks every hour, and one bandit steals 3 bricks every hour, to determine how long it would take 8 workers and 5 bandits to lay 1400 bricks, the following calculation must be performed:
- 10 - 3 = 7
- 5 x 7 + 3 x 10 = X
- 35 + 30 = X
- 65 = X
- 1400/65 = X
- 21.53 = X
Therefore, it will take 21.53 hours for 8 workers and 5 bandits to lay 1400 bricks.
