Question

If Anil takes 5 days to complete a task when he works for 8 hours a day, how many days will he take to complete the task if he works 6 hours a day?

• A. 6 2/3 days
• B. 7 1/2 days
• C. 7 2/3 days
• D. 6 days

Answer 1

Answer:

A. 6 2/3 days

Total work remains constant.

Calculate total work

$\text{Total work} = 5 \times 8 = 40 \text{ hours}$

Find required days at 6 hours/day

$\text{Days} = \frac{40}{6} = 6\tfrac{2}{3}$

$\text{Days} = \frac{40}{6} = 6\frac{2}{3}$
