mana pergi rm1? - ini jawapannya

How do you feel if I say the RM 1 wasn’t there in the first place?

Okay, let’s not confuse you more. Here’s the answer.

Each person paid RM 9 (RM 10 - RM 1) to the receptionist.

Amount paid RM 9 x 3 = RM 27

From that RM 27, tips given to the receptionist = RM 2

Therefore, RM 27 - 2 = RM 25

See that? You MINUS the tips, not add it on. This is where readers are tricked. The tips were paid using the existing RM 27, they didn’t add extra money to pay for the tips. So…

RM 25 rental + RM 5 discount = RM 30 original rental price

Bingo!

P.S.: Congrats to my friend Hasni who managed to solve this :-)

so complex...too heavy for monday since i am so blur today :)

maya,
takpe2 lain kali i cari teka teki yg lebih mencabar minda bagi u try ;-)

nisa,
ingat tak kat tepeng dulu (i think during one of the motivation lectures) ada cikgu bagi soalan lebih kurang mcm ni, tapi tak bagi jawapan. i pun takleh jwb time tu. skrg baru boleh!

k liza,
hahaha.. looks easy but not so kan? brain exerciser ;-)

hmm.. cik. maaf ya saya orang baru
xbrape nk paham. tp jalan kira yg sy
pk camni.

ok

katakan kawan 3 org nama A B C
ABC smua kelua rm10 kn.
so,


A B C
10 10 10


so jumlah rm 30.


apabila diorang dah kelua rm30, tbe2
diskaun rm5 kn.

so, 30 - 5 = rm25.

maknanya sorang kelua rm8.33 (rm25/3 org)

A B C
8.33 8.33 8.33

so apabila budak hotel tu ckp nk bg balek rm1 kt semua orang,
maka tiap2 org akn dpt rm9.33 (rm8.33 + rm1)

maka jmlah yg diorang dpt balek = rm9.33 x 3 = 28

ok end of part 1,

tp nk kira balek, xbole pakai jalan kira
10-1 = 9 sbb kali ini tidak ikut hukum matematik BODMAS. turutan jalan kiranya mengikut jalan cerita.

patutnya (10 seorang x 3 = 30 - 5 = 25 / 3 = 8.33 + 1 = 9.33)

sbnarnya jalan kira yg diberi tu adalah salah. tidak boleh diganti dengan jalan kira mudah (rm10 - 1 = 9) sbb
nnti ia akan mengubah struktur kiraan matematik yg dikira pada awalnya.

eg. 10 - 1, x 3 tidak sama dgn
10 - (1 x 3) kn?

sy pn xsure sngt. kakak2 abg2 klw saya salah tlg ajarkan. tq

aires,
hi there :-) adoilaa complicated nya jalan kira kakak abg awak tu, dua tiga kali baca baru i paham. anyway, the calculation does make sense. nampak lagi educated.. hehehe!
