Good at maths?? lets c?

i wana buy a spec at 97ringgit.. so i borrowed 50ringgit from two frens.. i paid to the salesman and she returned me 3ringgit.. i kept 1ringgit and return 1ringgit each to my frens.. so i owe them 49ringgit each.. 49x2=98.. then plus 1ringgit i kept equals 99ringgit.. so where is another 1ringgit???????

This is very very very very very very very very old.





There is no logic behind adding the 49 ringgit you owe to both friends to the one ringgit you have yourself.





The seller has 100 ringgit. You have a spec and 1 ringgit. You owe your friends 49 ringgit each. When you repay them you will be down 97 ringgit, which was the cost of the spec.

Reply:the ringgit is with U
Reply:The total value you possess ringgits and specs, and the total value they possess ringgits = 100 You can't mix what what they have with what you owe them.


What you possess, you owe them.


After you pay them each 1 ringgit, you owe each of them 49 ringgits for a total of 98 ringgits. But you possess 1 ringgit and a spec worth 97 ringgits for a total of 98 and the equation balances.
Reply:Another example of doing the math wrong.


2*49=98 You owe.


Plus


2*1=2 That you gave them.


98+2=100

Reply:the money u paid to shop: 97





now u owe them 98 in total, because there is still one dollar left in your hand. hence: 98 - 97 = 1 (in your hand)





Its a right equation.





you cannot add 98 (the money u owe them) to 1 (in your hand) because they are not from the same category.
Reply:You're keeping track of the wrong quantity.





Here's how it ends up:








2 × 49 - 1 = 97 = price of spec.





That is the correct relation, and it works out just fine.
