A team of 5 people took 8 days to finish an assignment. If one member leaves the team, how much time will it take for the team to complete the same assignment?
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.
