Math Question

You borrowed RM25 from your mom and RM25 from your dad.
So the total money you borrowed is RM50, correct?
Then, you spend RM45 on clothes and so you are left with RM5.
You decide to return RM1 to each of your parents, so you give your mom RM1 and you also give your dad RM1.
Now, you owe RM24 to both your mom and dad. You are left with RM3 in your pocket.

RM24 x 2 = RM48
but
RM48 + RM3 = RM51
???
Where did the RM1 came from?

Try to solve this. It really is a brain teaser.
If you get the answer, post a comment in this topic.
Have fun!! : P

credit and cash transaction are treated separately. why bother adding 3 to 48? 48 is the amount in arrears, NOT the amount held in hand. 3 IS the amount held in hand.

circulation of money:
1) 50 at the person

2) 45 at the cashier
5 at the person


3) 45 at the cashier
3 at the person
1 at mom
1 at dad

amount in arrears pusing kot mana pun, 25 each. tp dah bayar, jd 24 each.

erm..when reading this the first time it sure does seems a bit confusing at first, but when you give a second though on it you will see what is wrong actually..
well simply said that the total amount of money should be counted using the formula: amount amount
spent + balance
not amount amount
debt + balanced
using the right formula you will get : 45(pay to cashier) + 2(pay
to parents) + 3(balance)
= 50

salah..
rm48=rm45(for the thing)+ rm3( the balance u have)

its not sum both of them >.<

haha the trick is so simple..

it begins when u start to give each of ur parent rm1 each, while u keep another rm1 to urself.


why bother give rm1 each while u shud give them rm1.50 instead..

this is where the rm1 came from..haha,. nice2

i see..u dont get what i mean.

u got balance in ur hand rm3 rite? it's ur parent's obviously..none of them is yours.

but, instead of giving ur parent all of the money, u kept rm 1 with u..why??

suppose u give them equally rm 1.50 each, that would mean the remaining debt is
rm 25.00-rm 1.50= rm23.50

now, 23.50 x 2 = rm 47.00

rm 47.00 + rm 3.00 = rm 50.00

ain't it?

clearly now u see..the trick begin when u kept rm 1 to urself..
had u given out all the rm3 money to ur parents, the trick couldnt happen..hehe

tunsyed10 said...

that is correct
hehehe
