Because price of the goods depends on the no of digits in the value.Since number of digits in 913 is equal to 3 ,So he needs to pay only $3.

ReplyDeleteHe is buying house numbers. To buy 1 number, it costs $1, to buy 3 numbers it costs $3. He is still buying only 3 numbers, and so it only costs $3.

Deletehe never stated what he was selling

Deletei thought it stole the rest

DeleteI thought that he needed 913 but he only bought 100

DeleteI figured that one digit is $1

Delete913 is 3 digits so it would cost $3

He was buying a house #

I've already heard this riddle before... :P

Deleteur right

DeleteIts true its never stated that this 1, 10, 100 is the number of pieces you buy. But its not said also that if it is peaces, how much will cost 9 pieces, or 99 pieces. If we the pack allows ot be wraped 9 at once, 99 at once and 999 at once, and the packs are what is expensive, and the items are free, then... Lets say if u have 1 computer, you buy rooter with 9 outputs, If you have 10 computers, you buy one with 99 outputs, if u have 100 computers you buy one rooter with 999 outputs. if you have 1000 computers you buy one with 9999, pay 4$. So basicly the seller is selling outputs, and he is showing only the number at wich the price is changing. I have also other crazy ideas. What if its some kind of sertificate selling ? Lets say for counts of sheep 1 sert = 1-9, 2 sert = 10-99, 3sert = 100-999. Like regresive taxing of your sheeps...

Deleteas he needs 913 items.....i think he purchased only 100 and paid $3

ReplyDeleteawesome nand... i donno whether the answer is right. but i liked the way you interpreted it.

ReplyDeletei guess, it was a number which the guy was selling may be to print on a T-Shirt or something and as 913 is a 3 Digit number he charged him $3

ReplyDeleteMay be this is the correct answer!

DeleteMy guess is ...

ReplyDeleteIf 1 is for $1, 10 for $2, 100 for $3, then by analogy, 1000 will be for $4.

Buy 1000 for $4 and sell 87 for $1 back to the shop-keeper. The shop-keeper would readily buy 87 for $1 since its selling price will be much higher than $1 :)

So, the customer can still get 913 for $3... :)

My thoughts exactly

DeleteHe was buying house numbers, you're over thinking it.

DeleteThis is a sort of combination of geometric+arithmetic series.By the rates mentioned,1000 items will cost $4.Anything from 1 to 10 pieces will cost $1,anything from 10 to 100 pieces will cost $2so going by this rule,since 913 is between 100 and 1000,it will cost $3.

ReplyDeleteyou needed 913 but you only got 100 making the price $3

ReplyDeletetake 6times 100 for $18

ReplyDeletetake 41times 10 for $82

sold 97times 1 for -$97

so total items = 600 + 410 - 97 = 913

total price = 18 + 82 - 97 = $3

Nonsense.

Deletedang i'd have never thought of that XD

DeleteHes selling house numbers. Each digit is $1

ReplyDeleteThis comment has been removed by a blog administrator.

ReplyDeletethe shop sells house numbers. one house number cost $1 (9). two house number cost $2 (91). three house numbers cost $3 (913)

ReplyDeleteit's in binary

ReplyDeletethe shop sells house numbers

ReplyDeleteit has some pretty good sales

ReplyDeleteThe shop sells birthday candles, ex: "1", "2", "9". All at a dollar a piece.

ReplyDeleteYou were buying numbers for your house and each number is worth a dollar

ReplyDeleteYou were buying numbers for your house and each number is worth a dollar

ReplyDeleteHe already had 813, saying it was a craftable item produced with natural resources. With the given info, He had mad 813 but was too tired so he eventually decide to pay for the 100 remaining which only cost

ReplyDelete$100

Edit: $3 for the 100. (:

Deletebe one hell of a negotiator

ReplyDeleteA heck of a negotiator, man!

Deletelol

It is becuse of the number of digits in the number, that willbe the price. (EX.) 5,170, $4/ 6,000,000,000, $10

ReplyDeletejust like buying digits for ur cars number plate

ReplyDeleteThe shop keeper is killed, the items stolen, out of poor morality $3 is given to the store.

ReplyDeleteLOLOL all you guys! He needed the house number 913, he bought 100 signs for 3 dollars.

ReplyDeleteThats just weird.

DeleteThe guy bought 913 specks of dirt XP.

ReplyDeletehouse numbers! 1 dollar for each number

ReplyDeletedang XD i knew the answer you guys are all wrong........ lol.. Seriously? house numbers?

ReplyDeleteits VERY obvious..

It is Clearly Menitioned that Shop that "Reads"...

ReplyDeleteBut hasnt mentioned that what to

Buy...

he needed 913....but he still bought 100 for $3

ReplyDeleteHe bought 100 and stole the rest

Deleteoh

ReplyDeletei changed it a little and thought it was an address like 913 was the address and well sense their were 3 numbers in the " address " the house only cost three numbers. The riddle can be changed to were it fits my solution or at least were it make's my answer not as confusing.

ReplyDeletesorry, little mistake , it was really " three DOLLARS ". :D

ReplyDeleteFollow some key points to do well in CAT 2013 exam:

ReplyDeleteBasic conception should be clear

Taking self online mock tests to enhance your ability to score well

Sound preparation

Lot of practice

Self confidence

I agree the answer should be that he was buying house numbers, however it could also be said that the shopkeeper was selling packs of items (for arguments sake lets say packs of wolves :P) and each pack contained 83 wolves. If he bought 1 pack for $1.00 and 10 packs for $2.00 he would have 913 wolves (11 x 83 = 913).

ReplyDeleteOr maybe because he just gets them cheap from the shady guy on the corner

ReplyDeleteHE IS JUST STUPID

ReplyDeleteThe man bought an organic that can procreate.

ReplyDeleteOne does not need to buy 100 apple trees to get 100 apples, if you get my drift.

1 digit is $1.00, 2 digits is 2.00, 3 digits is $3.00

ReplyDelete1000 for 4$... and 100-1000 everything 3$... so 913 3$

ReplyDeleteThey need their house number which is 913 so $1 for each digit which means $3 because $1 add $1 add $1 is $3. Duh!

ReplyDeleteThankyou for the above information.

Assuming that each dollar multiplys the coorosponding number by 10 since 913 is in the hundreds place and 100 and 3.00 are corresponding divide 913 by 33.3333 which is 100 divided by 3.00 do this 4 times because the next step up is the thousands place then multiply by three and out should give you the amount due

ReplyDeleteHow about this:

ReplyDeleteYou buy 1000, which adds up to 10x3$=30$

Then make the argument that u dont need the 87 of them, so u can sell them back to the shop, this price would be 8x2$+7x1$=27$. This making the total price 30$-27$=3$
