The bad numbers (number T you can't find integer solution for 6x+9y+20z=T) after 20:

21, 22, 23, 25, 28,
31, 34, 35, 37,
41, 43.

And after that, every number is good. So N=44.

(Note: only need to check 6 consecutive numbers.)

we have to fill all these slot: 6n+1, 6n+2, 6n+3, 6n+4, 6n+5.
6n+1 gets filled by 20+20+9=49
6n+2 by 20
6n+3 by 9
6n+4 by 20+20
6n+5 by 20+9.

so start looking backwards from 49.

47 = 20+9+6+6+6
46 = 20+20+6
45 = 9+6+6+6+6+6+6
44 = 20+6+6+6+6

so, 44 is the answer...

I find 44 is ok

N=1

I didnt get this properly but if I got it right, then N is 1 as above.

N=set of all (+ve)numbers. This is trick question.
For any number, this condition will hold.

@jogi can u explain

Suspicion - Jogi hasn't got the question probably (no offense, ok?)

N = 1.

How will buy exactly 2 chicken nuggets? Buying 6 to say "I get 2, don't I" is an idiotic answer.


Lookup Frobenius Problem.

I seriously can't understand how someone can solve this during interview without knowing Frobenius problem n=3 formula... What is this questions trying to test? How better we rememeber formulas???? :-S

oops, 35 is good, but since 34 and 35 are bad, it doesn't matter...

The question doesnt say we we need to buy "exactly" N nuggets.. It only asks if there is a number N such that for any number greater than that, we will be able to buy that many nuggets.. So it is valid for any number.. Could someone please tell me if i am looking at the question wrong?

how to represent 46?

20+20+6=46

how to represent 97

6+6+6+6+6+6+6+6+9+20+20 = 97

the answer has to be 44 especially since it is an exact replica of the problem used to demonstrate the Frobenius problem.

42

Would you like fries with that?

how do u get odd multiples of 10.... like 10, 30, 50, 70???

it's 59

It is 43. after that all numbers get satisfied

Admire your persistence Zeally.

A McNugget number is a positive integer that can be obtained by adding together orders of McDonald's® Chicken McNuggetsTM (prior to consuming any), which originally came in boxes of 6, 9, and 20. All integers are McNugget numbers except 1, 2, 3, 4, 5, 7, 8, 10, 11, 13, 14, 16, 17, 19, 22, 23, 25, 28, 31, 34, 37, and 43. The value 43 is the number after which any number can be represented as the combination of 6,9 or 20. Therefor n=43

Wow.. I did not know McD had such a cool history!

The Number N after we can buy any number of Chicken Nuggets is 43
I will divide all no's in to 3 sets 3n,3n+1 and 3n+2.
If we look at 6 - 3n,9 - 3n and 20 - 3n+2
Now we can generate any 3n Series from 6 to infinity .....so 3 is the no that is not possible
for 2n+2 series..we can generate any 3n+2 no starting from 26 (20 +6 (since 6 is the least no) )....Highest number is 23.
The problem is 3n+1 series..first no that is possible in this series is 20+20 = 40...From 46 onwards we can all the numbers in this series....so we are left with 43...
So 43 is the Highest number beyond which we can but any number of Nuggets using 6,9 and 20.... :)

How do you make 91?

How do you make 91?

How do you make 91?

its 180
20 set chicken nuggets * 9 = 180
9 set chicken nuggets * 20 = 180
6 set chicken nuggets * 30 = 180
