Solution

The correct option is **D** 10 days

If there are less people on the team, the time taken to finish the assignment will be more.

∴ This is a case of inverse proportion.

If one person leaves the team, there will be 5-1 = 4 people on the team.

Using the formula for inverse proportion,

Number of team members × Number of days = constant

⇒ 5 × 8 = 4 × Number of days

∴ Number of days required = 5×84=10 days.
