cost of bonbons is greater than one of the other two by 3 and (5,7,8) doesnot satisfy the condition... hence the only answer is (4,6,9)

Yaa... I thought F(x)should be less than 1000 ... thanks for verifying

@3ala2, there are more values of F(x)

@all, the answer is 0.5 and this can be easily achieved by seeing x as 10^0+10^1+....+10^19=(10^20 - 1)/9.. and so on..
but i wanted a different method to solve it... and the answer is precisely 0.5

@doctor moshe, yeah this was the answer i wanted...this was how i first solved this question after which i found out the geometric progression method....

if x=111....1 (20 digit no., all are 1's), y=33...3(10 digit no., all are 3's) and z=44...4(10 digit no., all are 4's)..
find the value of (x-y^2)/z

46!!! now thats odd... lemme see..
so 3=2^2-1
7=3^2-2
46=7^2-3
so the next one shud be 46^2-7=2109
dood i am getting good at this.. woo hoo

this one is similar...
2=2^1
4=2^2
16=4^2
65536=16^4
hence the next member shud be 65536^16 = 1.158*10^77 ... tats huge...

not sure but considering the numbers as powers of 2, the sequence becomes 0,1,1,3,5,...
2*0+1=1;
2*1+1=3;
2*1+3=5;
hence, the next number will be 2*3+5=11

therefore, the next member of the sequence should be 2^11=2048

I dont know if this is correct but since fairy princess gets the first chance & shud get majority of the votes and everyone is greedy, she can propose that she gets 1/4th of the candy along with 3 others , say the ghost, the goblin and the mummy... and these 3 people will obviously agree since they get 1/4th instead of 1/5th if they split legally... thus fairy princess' proposal can get the majority
