Can you solve the problem?

Do you know this problem? tell me how you plan to solve this. You want to buy an item costing Php97 (Php is the monetary unit). Since you have no money with you, you asked your 2 friends(X,Y) to lend you some money. You borrowed Php50 each that sums up to Php100, then you're off to buy the item. Since the item only costs Php97 you have a change of Php3. You gave Php1 to (X) and another Php1 to (Y). So now your debt is only Php49. 49+49=98 then, you still have Php1 with you 98+1=99 Isn't it that it's supposed to sum up to Php100. Where is the other Php1? Actually, the answers lurking in my mind are yet to be justified. I just want an explanation regarding this. Another question is.. Is math an exact science?

Did you use PhP (Philippine Peso) as the monetary unit because you're Pinoy? If so, well... I'm Pinoy too =P ← OT I've heard of this problem too and honestly, I don't know the solution. But one thing I don't understand. Why would you add the remaining Php1 to your Php98 debt? I asked the person who first told me this problem, and it seemed she didn't know why xD To make an equation that makes sense though, you should subtract that Php1 (give 50cents each?) to the Php98 to get Php97 <<< which was the cost of the item... errr...   |

"Is math an exact science?" -- what a laughable question! Of course it is, if you do it right! Really, I had more trouble understanding why this was a tricky question than I did solving it. Right away when you added the left-over to the debt cumulation, it was clearly a mistake. Confusing debt with assets is a really bad mistake; I only wish the IRS would be so easily fooled!

xD I agree what Gendou said. And that is the tricky question? 0_0 What's wrong with just pay each lender PHp 50?! You owe them PHp100! It's a debt which you use PHp100 to acquire an asset worth PHp97. The remainder PHp3 can be retained while you accumulate the amount to repay the debt. If you are an accounting student, omg, please do your homework, I beg you. |

⇑ indeed. of course Math is an exact Science. if the answer's not right, there must be an error in the solution. Solution: Let you = z;
1st scenario : z borrowed 50 from x & y
x = -50
y = -50
z = 100
0
2nd scenario : z returned 1 to each
x = -49
y = -49
z = 98 [1 + item]
0you shouldn't add your debts to what you have.    m y . L i F E . i . t r a d e . i n . f o r . y o u r . P A i N . |

...it's not suppose to sum up to 100 it should be 97 instead of 100 when you still have 1 php your debt should be 98-1=97 after you pay 1 php for each person, it should decrease your debt not increase! and yes math is an exact science.

@aeris: 98 + 1 = 99, this is basically saying you increasing your debt as you pay them... why is it so hard, debt = 100 paid 2 current debt = 98 your actual debt is 97 because you should pay the last 1 php if u still don't understand this, don't focus on the wrong fact that it suppose to sum up to 100.
