I have a question
In how many ways a 3 digits number can be formed using digits 2 and 3.condition is that numbers can be repeated but there should not be a number in which 2 is repeated side by side.
for eg
233,232,333,323 -allowed
but 223,222 is not allowed


I want detail explanation how can we find this

Regarding below bogus puzzle which is making m for mockery of macth:
x + y^2 + z^3 = 5 + 3^2 + 1^3 = 15
Why we are just talking about 5 3 1??

Why this time Mr. Admin has not considered 0 as a natural number???
Why following combination is not considered as a valid solution:
14 1 0.
As per wikipedia of which the Admin is very fond of:
"By most definitions 0 is a natural number, and then the only natural number not to be positive."
http://en.wikipedia.org/wiki/0_(number)

Come out with your funny counter argument, lets see what you have to say this time. or
Scrap this question from this weeks puzzle if there is no logical answer

Yesterday's puzzle has Option 5 and not option 4 as answer because
5,3 1 is also a solution to
x + y^2 + z^3 = 5 + 3^2 + 1^3 = 15

Thus option 4) is wrong.

I was in dilemma whether to give answer for yesterday puzzle as 5 or none of these.

So I decided to leave the qn.
But surprised to see that there is a new answer which has no justification.
Only Viru Sihag may justify the answer.

It is simple m for murder of maths .

@ Admin,

Pls check yesterday puzzle.

Three natural numbers x, y and z are such that x + y^2 + z^3 = 15
How many set of values of x, y and z are possible.

Five sets are possible if zero is not considered as natural number.

If zero is considered , then answer will be
none of these.

in any case, four (4) can not be the possible answer.
Pls solve and confirm the solution before accepting the answer.

There is no universal agreement about whether to include zero in the set of natural numbers: some define the natural numbers to be the positive integers {1, 2, 3, ...}, while for others the term designates the non-negative integers {0, 1, 2, 3, ...}.

There is some confusion in today's puzzzle about natural numbers.
Pls clarify which definition is being considered here.
whether zero(0) is considered as natural number or not ?

@Ashwani,

Pls check this.

If their present ages are a and b respectively, then
a+b=91
b=91-a

When age of A was b yrs old ( (a-b) yrs earlier), then age of B was b-(a-b) =2b-a yrs.

As per given condition,
a= 2(2b-a)= 4b-2a
or 3a=4b where b=91-a

3a= 4*(91-a)
7a= 4*91
a=4*91/7 =4*13 = 52 yrs

A tells B when I was half of your present age you were 1/4th of my present age. If A’s present age is 36, what is B’s present age?



30 years
My present age is 36 and let your present age be x.
then
when you(B)were 36/4 = 9 yrs old, my age (A)was x/2 years
so
(x/2) -9 = 36-x
x-18 =72-2x
3x= 90
x= 30 years

@Vignesh: Assume that the age of his dad before 15 years is "D" and his mom is "M" and age of son is "S". And given- D=7*S & M= 6*S & D=M+5.
Now put the value of D and M in last equation and you get S=5 , D=35 & M=30 after 15 years the age of Dad , Mom and son are 50,45 and 20 and sum =50+45+20=115.
