Gonna post a quiz:
I borrowed 50bucks from man A, and 50bucks from man B.
I have 100bucks now, soon, i spent 97 on a pair of shoes.
so i m left with 3bucks.
I returned 1dollar to man A and man B each.
which means i m still owning 49dollars to the both of them.
I now have 1dollar after returning 1 dollar to each of them.
49 times 2 = 98
98 plus 1(which i have remained)
its 99bucks...

so where did that missing 1dollar went to??
Answer (by my brother)^^:
its a wrong way to calculate the answer, thats why
For example, i borrow 50 from A and 50 from B
then buy some sweets that cost 5 bucks, left 95 bucks
return 20 bucks to both A and B 20+20=40
still owe them 100-40=60 bucks
and i left with 95(after buying sweets)-40(which returned to A and B)=55 bucks
60+55=115 which is not 100, so this way of addition is wrong
U cant add what you owe with what you are left with
Here's how it should be done:
At first, u owe them 100 bucks. then u returned 2 bucks to them later on so u still owe them 98 bucks
this is the same as borrowing 98 bucks from them cuz the 2 bucks are just a take-and-return
the shoe cost 97 bucks and u have 1 buck in your pockets
97+1=98!!!
nothing is lost.....cuz its the same as borrowing 98 dollars from them, u spend 97 bucks and left 1 buck, but all the money u have are borrowed and u still have to return 98 bucks!!
Get it??
