------ pls wait 3+ days (Longer if you find it easy or trivial) before posting answers or hints.

1. in a Room of 100 people, 99% of them are Spinkos.

How many ppl must leave the room

to bring down the percentage of Spinkos in the room to 98% ?

1. 99% Spinkos = 1% non-Spinkos

98% Spinkos = 2% non-Spinkos

Interpreting "must" as looking for the minimum, we want the same set

of non-Spinkos to become twice as much of a percentage of the total,

so the total must become half its original value, i.e.

Start with 99 Spinkos, 1 non-Spinko (99 is 99% of 100, 1 is 1%)

50 Spinkos leave (this is the answer sought)

End with 49 Spinkos, 1 non-Spinko (49 is 98% of 50, 1 is 2%)

2. By the same argument, the minimum is for 500 Spinkos to leave.

If it doesn't need to be the minimum, then we can optionally have up

to nine additional sets of people leave, where each of these sets

includes 49 Spinkos and 1 non-Spinko. (This wasn't an option for #1,

as such a set leaving would leave zero people in the room.)

i could only think of Sun's (light) rays as

doing the searching and glaring and looking.

Yes. What if the people leave randomly, rather than exclusively selecting non-Spinkos?

Or exclusively selecting Spinkos, rather.
selecting non-Spinkos?

Anyway, the minimum number possible is the same as if only non-Spinkos

are selected, and the maximum number possible is whatever brings the

number of non-Spinkos down to exactly 1. It's also possible to fail to

hit the desired new percentage entirely, if the last non-Spinko is

removed before it's hit.

What's the average number, if we discard those failures? If the minimum

and maximum are equal, then obviously it's that number. Otherwise, it's

a question of which specific totals (of Spinkos and non-Spinkos removed)

are possible, how many ways there are to reach each one, and how many of

those ways also hit the percentage at some earlier point first.

Reminds me of the fruit drying problem. You have ten pounds of fruit. It is 99% water.

How much does it weigh when you have dried it out so that it is 95% water.
