Welcome, Students of the University of Peradeniya!

Here’s a small little problem for you all!

We’ll award the winning group LKR 20,000! *

You are a contractor leading a team of 30 people and your team has been assigned 30 tasks. Your boss insists that your team should solve these tasks in the minimum possible effort.

Fortunately for you, you know exactly what your team members’ strengths are and you’ve estimated the number of hours it would take for each member to solve each task (see attached csv). Every person should perform only one task.

Find the shortest total time for your team to complete all the 30 tasks.

For example, if you had 2 members in your team solving 2 tasks and their estimated efforts are as follows:

The most optimal allocation is Person 1 does Task 1 and Person 2 does Task 2.
Total Time taken = (1 + 3) = 4.
