Assuming these are truly team tasks and not activities which are solely performed by an individual, I'd look at a team-level metric such as throughput based on the existing team size/skills. Then, you could present a justification to management based on an improvement in throughput resulting from the addition of a team member. If you have good historical data, then a Monte Carlo simulation could provide you with a confidence range for how many tasks could be completed within a given amount of time. However, adding someone will only help if the work being done is not optimally staffed to begin with and if the main bottleneck to "doing more" is the team size. Kiron ...

Thanks Kiron, I did not elaborated my question correctly - sorry for that. The work that I am estimating is new scope, not being done by team currently. I worked with team to come up with a proof of concept and then we decided that this new task will take average 10 min. The duration might change when we will actually start work on it (only if the scope is accepted with resource assigned) - depends on attitude/efficiency/motivation of additional person we will hire. My current purpose is to justify the time that will be spent on these tasks in the duration of the project, which will be several months. I am gonna use the 80% and 20% suggestion from Keith. Do advise any improvement. Thank you.
Let me ask the question: does the completion of one of these 10-minutes tasks add value? Unless, reporting one of them as completed is significant, I would consider using a bucket activity to contain all these tasks. Then, you just have to assign a percentage of a resource to complete the "activity" over a set duration.

I have bucketed all these task and have come to a conclusion that I need an additional resource if I have to fulfill these tasks since these were not in the scope earlier. This is going to bring value to customer and they understand it. I know a rough quantity of such tasks that the project will receive in a month and now I am estimating resource(s) for it. I will be presenting a justification for mandays and I will be questioned on the time i am estimating. I will use the approach suggested by Keith to use 80% efficiency that the resource will be effectively working. Thanks.

A fairly standard estimate for how much time people actually dedicate to a project when assigned full time is 80%. Non-project team meetings, training, performance management, 5S, doctor visits, etc. is the other 20%.
If you have data on how many tasks you actually complete, use that metric. If not, you could assume 10 minute tasks but a 6.4 hour day as a basis for estimate until you get better data. ...

Thanks Keith. This helps. Thanks for the guidance. Yes I wanted to project the practical efficiency of the additional resource.

That's a sound approach Vipin.
I agree with Keith and Kiron.
