Q:

Logical puzzle

At a restaurant, how could you choose one out of three desserts with equal probability with the help of a coin? What if the coin is biased and the bias is unknown?

Answer

Our solution:


Toss the coin twice.
Let TH, HT and TT correspond to the three choices.
And if you get HH, just repeat (so it takes 8/3 tosses on average).


BIASED COIN

If the coin was biased, TH and HT would occur with equal probability.
So you could assign THHT, HTTH and THTH to the three choices, with other 4-toss outcomes rejected.
Or you could assign HTT, THT and TTH to the three choices, with other 3-toss outcomes rejected.

A) 2 B) 3
C) 0 D) Can't be determined
 
Answer & Explanation Answer: B) 3

Explanation:

In the given number puzzle,

Sum of Row 1 = 14

Sum of Row 2 = 23

Sum of Row 3 = 13 + ?

 

Sum of Column 1 = 16 

Sum of Column 2 = 23 

Sum of Column 3 = 11 + ?

 

Diagonal 1 sum = 17

Diagonal 2 sum = 14 + ?

 

From the above analysis,

Sum of Row 2 = Sum of Column 2 = 23

Sum of Row 1 = Sum of Column 3 = 14 = 11 + ?    .............(1)

Sum of Row 3 = Sum of Column 1 = 16 = 13 + ?    .............(2)

Diagonal 1 sum = Diagonal 2 sum = 17 = 14 + ?    .............(3)

  

Hence,

From (1), (2) & (3)

? = 3

Q:

Puzzle : Sequence of numbers

Sequence of numbers are 1, 11, 21, 1211, 111221. What will be the next one in the above sequence?

Answer

 It is a strange sequence. Each number describes the resemblance of the previous one, except the first one.


11 describes the previous '1' which contains one '1'


21 describes the previous '11' which contains two '1'


1211 describes the previous '21' which contains one '2' and one '1'


111221 describes the previous '1211' which contains one '1', one '2' and two '1'.


So the next sequence will be 312211, that is the previous '111221' contains three '1', two '2' and one '1'.
