ahahahah kani maoy way answer daghan na maestro sa math ang naghilak ug naghikog tungod aning pangutanaha.

kabalo akong maestro ani.. pero wa gyud niya g tudlo.. dghan to kabuang nga math.. pero tagsa ra kaayo mo share..... wah! (

it's a trick question.

the TS states:

49 for mom
49 for dad

that's where the trick is. it should not have been that way.

it should be:

48 for mom
49 for dad
...or vice versa (could be mom or dad)

the kid should owe at least two pesos for one parent one way or another---since the kid took 1 peso off the change. because the change is an odd number, the peso value for each parent should not be equal.

simple algebra.

so if we equate:

48 + 49 = 97 (t-shirt)
97 + 3 (change) = 100.

hehehe..

sayop na man gud daan ang question sa TS..

dili nimo puede i-add imo utang ug imong napalit.. kay lain na sila nga math.

mao ni ang math..

nagasto:
tshirt - 97
cash - 100
change - 3


utang:
mom - 50
dad - 50

[nirdle_phogi]

very easy!
cos(xyz) = 3x + Ф + ∑(∆xy) / ∞ + (∮)
a = 100
so sakto diba

wahahaha.. nosebleed.

imong utang
49-mama
49-papa
98 total utang

97 tshirt
1pesos (with u)
98 pesos (equal sa total utang nimo)

kani o maoy sakto..

[gkoopir]

imong utang
49-mama
49-papa
98 total utang

97 tshirt
1pesos (with u)
98 pesos (equal sa total utang nimo)

Mao ni sakto.....^_^

[ManWhore]

wala gyud nakasulbad japun...

hahah. ka-funny, pero kabalo na ko. it's a matter of adding instead of subtracting.

50 from mom, 50 from dad.
97 is how much you payed for the shirt, nya 3 pesos change.

so, you're utang should only now be 97.

if i-uli nimu 1 each each to mom and dad, 49 each imu na lang imu utang nila. and you have 1 peso.

for example, i-uli nimu ang 1 remaining peso to your dad, 48 na lang imu utang niya. ergo 49(mom) + 48(dad) = 97 = your remaining utang = value of shirt.

let m=mom, d=dad, y=the money you have, s = shirt, u=your utang=rm+rd

since utang nimu, so
m = -50
d = -50

so, you gain 100
y = 100

shirt is 97
s=97


y = y-s
y = 100 - 97
y = 3

let rm=return to mom, rd=return to dad since you return one peso each
rm = 1
rd = 1

y = y-rm-rd
y = 3-1-1
y = 1

m = m+rm
m = -50 + 1
m = -49

d = d+rd
d = -50 + 1
d = -49

since u = rm+rd
u = (-49)+(-49)
u = -98

if you factor in y,

u = -98+1
u = -97

your remaining utang is 97, which is exactly how much you spent for the shirt. walay nawala.

epstacsis na ko..... simple ra kaayo ang tubag ana

100-97=3

ang sukli gi balik nimo ni:
mom=2
dad=1

so utang ni:
mom=50-2=48
dad=50-1=49

so 48+49=97 balik ra gihapon ang 97+3=100
