Question

Carpenter A can make a chair in 6 hours, carpenter B in 7 hours and carpenter C in 8 hours. If each carpenter works for 8 hours per day, how many chairs will be made in 21 days?

Accepted Answer

To find the total number of chairs, we first calculate the total working hours available for each carpenter over 21 days. Since each works 8 hours per day for 21 days, the total time for each is 168 hours.

Next, we calculate how many chairs each carpenter can complete within that time:

Carpenter A takes 6 hours per chair. In 168 hours, A makes 168 divided by 6, which equals 28 chairs.

Carpenter B takes 7 hours per chair. In 168 hours, B makes 168 divided by 7, which equals 24 chairs.

Carpenter C takes 8 hours per chair. In 168 hours, C makes 168 divided by 8, which equals 21 chairs.

Finally, we add their individual outputs together: 28 plus 24 plus 21 equals 73.

Therefore, 73 chairs will be made in 21 days. The correct option is C.
