1/5x + 18 = 1/3x
multiply all by 3
3/5x + 54 = x
subtract 3/5x from both sides
54 = x - 3/5x
54 = 5/5x - 3/5x
54 = 2/5x
multiply all by 5
270 = 2x
divide both sides by 2
135 = x
check answer
135/5=27
135/3=45
45 - 27 = 18
so then
135 * 4 = 540
540 - 135(number of them today) = 405

I got 45

Day before yesterday=Monday
Yesterday=Tues
Today=Wed
Tomorrow=Thurs
x=Wednesday
.2x+18=.33x

Solve for x
Then divide by 3(for Tues) and multiply times 4(for Thurs)

my only chance is if it a trick and when you count tomorrow then it would be today and today would be yesterday

I think I just confused myself

the answer is not 405, you did the same thing that i did and thought it said 4 times as many as today.
however it states 4 times as many as yesterday was 45
45*3=135
45*4=180
180-135=45

Er... no.

First of all, the News doesn't vary in its update time to "best give people in different time zones a chance..." That's the whole point of having a Neopian Standard Time. I'm not even sure how your way would make sense in terms of fairness. If the News or Lenny Conundrum were to be released at different times, then the person in the earlier time zone would get the advantage, would they not? The News/LC is released at the same (NST) time for everyone.


Neopian Standard Time is simply their way of saying Pacific Standard Time, so people in different parts of the world who are trying to be online at the same time [for instance, for a Battledome fight] can say, "I will be online at 6a NST" instead of having to do all the math of "Well, what time zone are you in..."

TNT varies at what time the news comes out every day - or at least they say they do. Meaning, maybe on Monday they'll release it at 5pm NST, then on Tuesday they'll release it at 8am NST, etc. It's their way of making it fair for people anywhere on the globe, because if the LC was always updated at a specific time? It might be totally convenient for someone, but it might be at 3am for somebody in another time zone.

I do hope that made sense; my brain's a little on the overfried side today.


Yes. This is what I meant to say, I'm sorry if my wording was awkward.

fmorel got it right - 45
1/5x+18=1/3x => x=9*15
t'morrow = yesterday * 4 = 4* x/3
t'morrow - t'day = 4/3x - x = 1/3x=9*5 = 45
I took me about as long as this page was loading ;P

The LC authors, in Round 163, wrote:
They started watching you the day before yesterday, when there were one-fifth the number of Meepits watching you today. Yesterday, eighteen more Meepits started watching you, but that was still only one-third of today's total. Tomorrow, there will be four times as many watching you as were watching you yesterday.

How many watchful Meepits will be added between today and tomorrow?

Let's label things:

. . . .number today: n

. . . .day before yesterday: (1/5)n = n/5

. . . .yesterday: n/5 + 18 = (1/3)n = n/3

Thus we have:

. . . .n/5 + 18 = n/3

Multiplying through by 15 to clear the fractions, we get:

. . . .3n + 270 = 5n

. . . .270 = 2n

. . . .135 = n

So there are 135 Meepits "today".

Since there were n/3 Meepits "yesterday", then there were 135/3 = 45 Meepits "yesterday".

Since "tomorrow" there will be four times the amount from "yesterday", then "tomorrow" will have 4(45) = 180 Meepits.

The difference between "today" and "tomorrow" is the number that will be added:

. . . .180 - 135 = 45

Just to clarify:

. . . .********************
. . . .****ROUND 163:*****
. . . .********************
. . . .***THE ANSWER IS***
. . . .********************
. . . .********"45"********
