A chemist has three different acid solutions. The first acid
solution contains `15%` acid, the second contains `30%` and the
third contains `50%`. He wants to use all three solutions to obtain
a mixture of `78` liters containing `35%` acid, using 3 times as
much of the `50%` solution as the `30%` solution. How many liters
of each solution should be used?
The chemist should use __________________ liters of `15%`
solution, __________________ liters of `30%` solution, and
__________________ liters of...

The quality department at ElectroTech is examining which of two
microscope brands (Brand A or Brand B) to purchase. They have hired
someone to inspect six circuit boards using both microscopes. Below
are the results in terms of the number of defects (e.g., solder
voids, misaligned components) found using each microscope. Use
Table 2.

write a python program that include a function named
activity_selection() and take in two arguments, first one would be
the number of tasks and the second argument would be a list of
activities. Each activity would have an activity number, start time
and finish time.
Example activity_selection input and output:
activity_selection (11, [[1, 1, 4 ], [2, 3, 5], [3, 0, 6], [4,
5, 7], [5, 3, 9], [6, 5, 9],[7, 6, 10], [ 8, 8, 11], [ 9, 8,...
