Dear Admin:
Today's Puzzle was too imaginative and can have multiple answers based on each persons imagination.
Option 9(4148) has the only option where all 4 digits were not unique and 4 was repeated two times. Hence option 9 should also be considered as valid answer.

Hi M4M team,

If your answer for Last Friday(08/06/2012) Puzzle is "k < 0 means only negative values are possible and k^2+9k-10 < 0 implies that (k+10)(k-1) < 0 implies that -10 but k is negative so answer will be -10" that is Option 4 (-10,0). But one of the root 0 is not satisfied k < 0 condition. Then why not Option 1 (-10,-4). Both roots are satisfied k < 0 condition.

Dear Friends,

For puzzle

96,45,16,3,0,?

next number will be 1.

Each number in series is given by
(x+1)*(x-1)^2
where x=5,4,3,2,1,0,-1....
when x=5, number is 6*4^2=6*16=96
when x=4,
number = 5*3^2=45
..
..
when x= 2, number = 3*1^2=3
when x=1, number = 2*0^2=0
when x=0, number = 1*(-1)^2= 1*1=1

Dear Admin,
In yesterday puzzle, fill the blank space
96,45,16,3,0,?
Consider differences:
96-45 = 51
45-16 = 29
16- 3 = 13
3 - 0 = 3
again take differences:
51-29 =22
29-13 =16
13-3 =10
so, next diff: 4; therefore, 4-3 = -1 +0 =-1 is the answer. plz check this answer (option 5) and provides points....

U asked only the number of zeros in the product. It means, it will have more than 54 zeros in the resultant. So, answer Option 10.None of these.

If You asked "How many trailing Zeros in the Product" means, it will have 49zeros.

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."

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.
