A while back, in a small village which the pipe piper had missed, there was a horrible invasion of disgusting rats. They crawled over the floors, the roofs, into the food, and basically made the life of the villagers a living hell.
One day, at a village meeting, many of the villagers were brainstorming, trying to find out how were they supposed to get
rid of the infestation.
Suddenly, amongst their midst, a wise old man stood up and said:” By golly, I believe I’ve figured it out!” All the villagers were shell-shocked, and demanded an explanation.
“Well, it’s pretty simple, you see,” said the old man, and began to draw a large diagram.
This was the very same calculations used.
Assume that the number of rats originally is x
Assume that the number of rats that a cat can eat is y
Assumptions proposed by the old man
24X-41Y=0
24X=41Y
X/Y=41/24
If the value was substituted into the equation, would the answer be correct?!?!?!
41-24=17
2(17)-24=10
3(10)-24=6
6(4)-24=0

KYUEM is a school situated in Lembah Beringin. Lembah Beringin, you ask? Yeah, it’s one of those secluded, minimally populated places deemed “far away from civilisation” by city-bred Malaysians. The nearest town would be Tanjung Malim, which, as undesirable AND depressing as it sounds, is the source of entertainment and leisure for those who are sick of being on constant lock-down on campus. Students head on over there over the weekends.
The lucky ones would call a taxi driver and not rely on the school’s transport system, like they would call the on-call matron. When you’re sick, you call the matron, because let’s face it, she’s almost always never there in the clinic. It works the same way. When you’re sick of trolling on the KY campus, what’s the next best thing? You troll in Tanjung Malim.
And yeah, maybe get a kebab or two at the night bazaar.
Speaking of bazaars, there is a particular stand that stands out from the rest every Saturday night. Nah, it’s not popular or anything. Nobody ever goes there. The owner of said stall is Salimi, and he sells nasty, slimy (Salimi=suh-li-my=slimy, geddit? Heehawhaw) satay which he calls Salimi’s X-treme Satay.
Some people say he’s weird (if selling nasty satay is weird enough, what else could top that?), and that he’s insane. The other vendors said that there’s a reason why he sells slimy satays. They say that the only reason that people actually let him set up a stall there is due to pity-- pity that the poor, bizarre man had lost his mind due to some weird incident. Here’s how the story goes:
Salimi used to be the top satay seller in town. His stock would be successfully sold off to hungry customers in five minutes since setting up time. He was a legend. Men wanted to walk in his shoes, and ladies wanted to be in his pants. SALIMI X-TREME wasn’t a pun back then.
Word is that the night before the bazaar, he would prepare the satays in his kitchen, called Salimi’s X-treme Kitchen. He would prepare x number of satays every preparation night without fail. One night, however, they all just disappeared!
Salimi waved it off at first, saying “Oh, my crazy fans. They must love my satays so much that they’d resort to stealing them. Hardeeharhar.” He let go of the issue, thinking it would be a one-time thing. He did not set up his stall at the bazaar that fateful weekend. He did go to the bazaar, however, winking at every single one of his fan, saying “Someone’s been very naughty last night.” That statement caused many to blush, as he was the best catch in town at the time. Salimi the X-treme Satay Legend.
The next time he prepared the satays however, it happened again! He prepared x number of satays, and it disappeared! He was a bit disgruntled this time. “This is costing me, how annoying.” He grumbled. “How do they, or it, do it? To carry off x number of satays, one would need a barrel.”
The following week, he doubled the amount of satays, and they all disappeared. 2x number of satays could fill up a car.
The next week, he tripled the amount of satays, and it disappeared. Now, x number of satays is hard enough to carry off by one person. Can you imagine 3x number of satays? He was like, “3X SATAYS?! HOLY—.”
Salimi, out of vengeance, prepared 4x number of satays the next time. He was a bit smug, seeing as to carry 4x of satays, one would have to bring in a truck. Much to his shock, however, they all disappeared!
Salimi had gone bonkers. For some absurd reason, he decided that to stop the disappearance of his popular satays, he would make disgusting ones. The disappearance stopped, and Salimi was happy. He could finally sleep in peace. Too bad his satays are nasty.
That was the end of his era. He was no longer a legend. No one wanted to walk in his shoes, no one wanted to be in his pants. Except for a drunken homeless man named Big Mikey, but that is irrelevant.
When I first heard the story, I was puzzled. Okay, carrying off x satays was hard. 4x satays? It’s not remotely possible. Nobody owned a truck big enough to fill satays up with. To house orgies for drunken, homeless men, yeah. But satays? HELL NAW.
Then, common sense filled my brain. I figured it out in a heartbeat. Okay, that was an exaggeration. I ain’t that smart, but I did it anyway. The math?
First night: x satays made. y satays taken.
x-y
Second night: 2(x-y) satays made. y satays taken
2x-2y-y= 2x-3y
Third night: 3(2x-3y) satays made. y satays taken.
6x-9y-y=6x-10y
Fourth night: 4(6x-10y) satays made. y satays taken.
24x-40y-y=24x-41y
41/24=x/y
Therefore, x=41 y=24
Substitute!
x-y = 41-24 = 17
2x-3y = 82-72 = 10
6x-10y = 246-240 = 6
24x-41y = 984-984 = 0
That’s a way to solve it, though it made me wonder, how the hell hard could it be to cart off 41 satays that you’d need a barrel. I imagine his satays had to have been extremely huge, back then
OH YEAH.

“Brains! Brains! Brains! We want brains!” chanted the filthy pack of zombies – well, only those with their lower jaws still attached to the skulls. The rest were content with making groaning and moaning unintelligibly.
“Please, give us more time! We’ll have enough ‘brain-nanas’ by the end of the year!” pleaded the Ken Clarke, village chief, quaking and trembling.
“What are these brain-nanas you speak of?” asked Count Zombrula, his head cocked to the left.
“They’re better than brains, juicier and squishier – with a bit of a crunch. Best part is, no cleaning up necessary! Here’s one, try it.” replied Ken, his anxious eyes flitting from one headless zombie to another, each more menacing and well, more stupid-looking.
“Hmm. Hmm. It is good. And I do hate cleaning up. The last feeding frenzy cost me my red Italian silk cape,” laments the Count
After mulling over the offer, he agreed to the change. “But”, warns the Count, wagging his finger, or rather, what’s left of it, “there must be enough brain-nanas for all of us, without fail. If you want to keep your brains intact, use them well”.
Ken Clarke, despite being looked up upon by the villagers, was hopeless when it came to mathematics.
Immediately after the zombies left, Ken ordered the villagers to start planting brain-nanas trees, and by the end of the year, there were X brain-nanas. The zombies left the village, satiated. To the villagers’ horror however, all the brain-nana trees began to wither and refuse to bear fruit, and they could only use the leftover brain-nanas to produce double the amount of the previous year’s brain-nanas for the year’s harvests in the 2nd year, triple in the 3rd year, and four times the number of bananas left over from the 3rd year during the 4th year.
Each year, there were more than enough brain-nanas for the zombies to feast on. The villagers were relieved. By at the end of the fourth year though, THERE WAS NO BRAIN-NANAS LEFT! The zombies had eaten them all.
How many brain-nanas did the villagers produce for the first year’s feast?
Legend: X – Brain-nanas produced
Y – Brain-nanas eaten by zombies.
X - Y = X - Y
2(X - Y) – Y = 2X – 3Y
3(2X – 3Y) – Y = 6X – 10Y
4(6X – 10Y) – Y = 24X – 41Y = 0
Therefore,
24X = 41Y
24/41 = Y/X
X= 41
Y = 24
