What is the minimum number of Bingo projects K could have worked on?
What is the maximum number of Bingo projects K could have worked on?
If it is known that K worked on 24 Bingo projects, what is the maximum number of projects that could have been Cr@p-that-Sells projects and vanity projects (otherwise known as stinkers)
If it is known that K worked on 40 Bingo projects, what is the minimum number of projects that could have been Cr*p-that-sells and Hit-or-Miss projects (otherwise known as Good-Stuff)
Once upon a time, there lived an artist named K in an interesting industry called K. Artist K gave many performances and became so popular that people started dissecting his role in the industry and history. Suckers!
Turns out K started his career making commercial art, or broadly cr*p that sells. Soon he became very good at a number of things and became very keen to create wonderful art that would stand the test of time. So, he started venturing into stuff that came to be termed as Hit-or-Miss projects. Somewhere along the line, K acquired a set of skills across the spectrum and was keen to highlight these extensively, and here came what would be called the Vanity projects.
As luck would have it, a great many of the projects fall into more than one category and that gets the mathematicians into it. The sweet wonderful projects that fall into all three categories are called Bingos.
Note: that all projects K worked on could be categorized into at least one of the three classifications provided.
Anyway, to cut a long story short, K worked on a total of 112 projects – 78 of whom were commercial projects, 69 of whom were Hit-or-miss ventures and a staggering 84 were vanity projects. Now, on to the questions.
