Hello sir,

Though I am not very good in calculating the complexities, but still I was wondering what will be the complexity of this problem, it has to be much less than O(n), I think the no. of iterations should be-

i>=n-(n/2-n/3-n/4-…..n/i), so can we say the complexity to be O(n) or are we supposed to solve this eqn to calculate the exact complexity?

Kindly give your suggestions and correct me if I am wrong.

guys this puzzle is very simple really …so let start
(1 + 1 + 1 ) ! = 6
2 + 2 + 2 = 6
3 * 3 – 3 = 6
sq root 4 + sq root 4 + sq root 4 = 6
5+5/5 = 6
6+6-6 = 6
7-7/7=6
cube root 8 + cube root 8 + cube root 8 = 6
SQ root of 9 * sq root of 9 – sq root of 9 = 6

so thats it. it is sipmle.i have solved it in first instance….enjoy

Comment on White and Black Hat Puzzle by Ajoy

Probably the question is worded wrongly because it says: “Number of times the king comes to council is equal to the number of caps of a particular color(either black or white).”

If that is so, then consider the following from the answer:
“Let us consider the case when only 1 person is wearing white hat. When the king comes in for the first time, that person observes that no one is wearing white hat but king has come in, that means one person is wearing it.”

Given the wording of the question, if the only person wearing a white hat does not see anyone else wearing a white hat, that person cannot assume that one person is wearing it. Everyone may be wearing black hats and the king has come in because he decided to come as many times as the number of black hats. The question should probably have said “… equal to the number of white hats.”

For Question 1: Ratio of boys to girls in village – I know that the answer that Ram gave is the expected answer; but I find this question itself to be incorrect. It requires making the assumption that the probability of giving birth to a boy or a girl is equal. The moment you make this assumption, you have fixed the ratio to be 1:1. If you do not make this assumption, then you really cannot say anything about the ratio. The 1st children of all 100 couples (say), there might be 20 girls & 80 boys. Then the 20 couples go for a second child and could have all 20 boys. That gives us 100 boys and 20 girls. If you assume at the outset that the probability of having a boy or a girl is equal, then there is nothing more to say. Also, EVEN IF probability of having a boy or a girl is equal, it does NOT mean that always half the couples will have boys and the other half will have girls. That is like saying that since the probability of heads or tails when a coin is tossed, is the same; it means that if you toss a coin N times, there will ALWAYS be N/2 heads and N/2 tails. Anyone with a little knowledge of probability and statistics could tell you that that is not the way probability works. I challenge anyone to prove that this question and the expected answer of 1:1 is valid.
