Question

If one worker can lay 10 bricks every hour, and one bandit steals 3 bricks every hour, then how long would it take 8 workers and 5 bandits to lay 1400 bricks?

Answer 1

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.
