Calculating Time to Complete Tasks

To calculate the time it will take the locksmith to complete 9/10 of the tasks, we can use the information provided. The locksmith completed 7/8 of the tasks in 14 units of time. We can use this information to find out how long it will take to complete 9/10 of the tasks.

First, let's calculate the time it takes to complete 1/8 of the tasks: - Time for 1/8 of the tasks = 14 / 7 = 2 units of time.

Now, we can calculate the time it takes to complete 1 task: - Time for 1 task = 2 * 8 = 16 units of time.

Next, we can calculate the time it takes to complete 9/10 of the tasks: - Time for 9/10 of the tasks = (16 * 9) / 10 = 14.4 units of time.

So, the locksmith will be able to complete 9/10 of the tasks in 14.4 units of time.
