who will give answer first?
give the answer of this question?
suppose u have Qr. 20. u have to get 20 items in qr 20.
one pen cast is = Qr 4.00
one pencil cast is = Qr 0.50
one ruber cast= Qr 0.25
now how may pen, pencil and ruber u will buy so that total number items=20 and there total cast= Qr 20 .
????????
but you aren't even close... :-)
i never take any thing personally....

ohhmmmm
lol
getting the answer for this question is easy
the tricky part is HOW you find the answer...
Skanky, I don't work for NASA
but you're close...
the name of the company I work for is an acronym in honor of a famous law of physics... hows that?
I will not name it but if any of you can figure it out, hats off to you...
And swissgirl... I drive you crazy? :'(... sniff... sniff...
:-D
Who you work for??? NASA???
That was a lot of info dude, I just took a piece of paper and do some simple maths... LOL
After some bad results I got the right ones...
The Venezuelan Sensation!!!
your answer is all over the place... its wrong...
5 pencils alone will cost 20...
you got your formula wrong mate
I have given the TWO answers as well as what I think is the simplest way to solve the problem (without using a graph)... let me know if anyone else has a simpler way to solve it
Let
a = pencast
b = pencil cast
c = rubber cast
formula : (4*a)+(b*.5)+(c*.25)=20
therefore 16a+2b+c=80 (multiplying both sides by 4)
therefore 15a + b + a + b + c = 80 ...........(1)
but given a+b+c=20, substituting in (1)
therefore 15a + b + 20 = 80
therefore 15a + b = 60
a can only be 0,1,2,3 or 4 because a or b are not negative
if a = 0 then b=60 wrong answer
if a = 1 then b=45 wrong answer
if a = 2 then b=30 wrong answer
if a = 3 then b = 15 and c = 2 possible answer
if a = 4 then b = 0 and c = 16 possible answer
that is, this problem has two answers...
3 pencast
15 pencil cast
2 rubber cast
or
4 pencast
16 rubber cast
I need that. Thanks, Skanky.

Sorry Everybody got late to answer gotcha question. actually a small boy came to his shop at 1:20pm, he had only QR.20 and his mom told him to buy pen, pencil and rubber and he must spend all QR.20 and total item qty should be 20 also. this Gotcha got confused and he asked this question to QLer's. but unfortunately at 1:51pm first answer came after 30 minutes, so this boy could not wait till time and left without buying anything. So sad for gotcha.................... LOL
Respect 4 Everyone
How you doing today???

3 Pens X 4 Qr = 12 Qr
15 Pencils X 0.5 Qr = 7.5 Qr
2 Rubers x 0.25 Qr= 0.5 Qr
Total = 20.00 Qr
I kill your post sorry.
The Venezuelan Sensation!!!
a = pencast
b = pencil cast
c = rubber cast
formula : (48a)+(b/.5)+(c/.25)=20
when a*4=20 ans=5
when b/.5=20 b=10
when c/.25=20 c=5
the answers are:
a=5
b=10
c=5
_Good friends are like stars........You don't always see them, but you know they are always there._
3 * pen=12
15*pencil=7.5
2*rubber=.5
total 20 items = QR20
congrat first one is wrong second one is right.
3 pens x Qr 4 = 12
15 pencils x Qr 0.5 = 7.5
2 rubbers x Qr 0.25 = 0.5
Both Total 20 items and Qr 20
all items should be included in 20 items.
so above one is right
[img_assist|nid=61229|title="impossible" it self says I M POSSIBLE !!!|desc=|link=none|align=left|width=|height=0]
3 pen = 12
15 pencil = 7.5
2 rubber = .5
12 + 7.5 + .5 = 20
3+ 15 + 2 = 20
4 pens x Qr 4 = 16
16 rubbers x Qr 0.25 = 4
or
3 pens x Qr 4 = 12
15 pencils x Qr 0.5 = 7.5
2 rubbers x Qr 0.25 = 0.5
Both Total 20 items and Qr 20
wow !!!
