81 gak..
tgk kaler kat bola la...kot

kEyNAh said...

kenapa 81??
hmm..
guna kaedah elimination..
yg dua first..
tggal yellow red= -1
yg second n third
blue red= +4
smakan yg kedua n keempat..
so, tggal blue red= +4..
tol x??
any comment??

kEyNAh said...

eh lpe lak..
so, the solution 77+4=81....

amaraman said...

the answer should be 73.
red=20
yellow=21
blue=16
maleh tunjuk jln kira..

rahman d said...

tak ada kene mengena dgn colour...jawpannya 80.....warna tuh sajer jer nak bagi keliru.....
78 sebelumnya 77....
81 sebelumnya 80...

leh terima ker anas??hehhe

amaraman said...

rahman mengarut! semua jgn layan dia. anas jgn layan rahman tu..merepek!

rahman d said...

itulah....soalan nih tak ada panduan pun...so dia tak ckp pun..warna2 dan bola2 api tuh berguna as an unknown...so jwpn aku tak leh dikira salah.........aku mmg setuju gak dgn jawpan kau ammar...tp bak kata amin..pikir luar kotak...hahahahahhaha

aku tetap ckp 80

Muhammad Anas bin Kamarudin said...

huhu... answer scheme says 73..
just like Amaraman said...
just add them up and you'll get the answer...

should be easy for those with add maths...

b = blue
y = yellow
r = red

b + 2y + r = 78 > equation 1
b + y + 2r = 77 > eq. 2
y + 3r = 81 > eq. 3
2b + y + r = ???

eq. 1 - eq. 2
y - r = 1
y = (1 + r) > eq. 4

eq. 4 into eq. 3
(1 + r) +3r = 81
r = 20

finish it off...

CONGRATS to those who got that answer!!

regarding Rahman D's answer... ada2 je korang ni... hmm... yeah... i'd say that's out of the box... betul jugak what he said...

+ math lg..-.-

org kampong said...

gne cr keynah dpt lg cpt
cmenye keynah salah kire..
cek btol2

77&78 : y>r (+1)
78&81 : b>r (+4)

? : 2b gnti ngan 2r=2(4)= 8
so 81-8=73

jd congak pon dah bleh dpt...
hehe

tp klo nk pgg prinsip luar kotak rsenye kurg sesuai,
sbb soalan IQ memerlukn sume clue yg dy bg,
sbb tjuan soalan dbuat bkn ntuk trick org tp ntuk challenge IQ...
bgus pgg prinsip luar kotak,tp kne pndi tgk konteks

p/s just an idea

cetakn komp. xmemerlukan t.tangan

kEyNAh said...

wah2!
ye la.. silap kira..
huhuu..
kira guna minda..
rupanya minda ada virus..
dah lma xkira utk math melainkan time comed ja...

Muhammad Anas bin Kamarudin said...

truth is, keynah wrote 81, so i didn't even bother looking at her 'jalan kira'... huhu...
