Cryptogram for deciphering-Rejoinder

The sentence starts with  number 26.As A and I are the only single alphabet words,26 can stand for for alphabet   A or  I.By logic we can start the numbers 26,25,24 etc with A,B,C etc or I,J,K etc or I,H,G etc or A,Z,Y etc.
By seeing all these options we can decipher the sentence.It is actually as follows-
A bird in the hand is messy.,

Sequence filling puzzle

There was a puzzle shown in Sunday Magazine New Indian Express 20 july 2014 as follows-
What number comes next in the sequence 1,4,5,6,7,9,11..
Although I can give a hint that it is an alphanumeric sequence (Having connection with numbers and  alphabets) -it was truly  difficult to find the answer.
You will be surprised the next number is 100.
All the numbers shown in the puzzle when expressed in words do not contain the alphabet T.
The only next number with this quality as you can observe will be 100..

Birthdays for twins-Rejoinder

This is with reference to my earlier blog where I had enquired how the younger child among twins could celebrate his birthday earlier than his older brother.
This is possible as per  the circumstances shown below-
At the time the mother went into labour,she was travelling east-bound by boat.The older twin was born first early on March 1st,The boat then crossed the international date-line (where the date  still relates to February 28th) and the younger twin was born at that time viz on February 28th.
In a leap year the younger twin will thus celebrate his birthday 2 days before his elder brother.

Cryptogram for deciphering

A cryptogram was published in Times of India paper of October 1st
A series of numbers were given,each number referring to a particular English alphabet and the whole group supposed to represent a message.
Following are the numbers
26,25,18,9,23,18,13,7,19,22,19,26,13,23,18,8,14,22,8,8,2
Unfortunately no hint was given about the number  of words involved and the number of alphabets included in each word.It was thus  difficult to decipher the message.
Let me give you this hint
There are 7 words and they are represented by the following group of numers .
26....... 25,18,9,23....18,13.....7,19,22.....19,26,13,23....18,8.....14,22,8,8,2
Can you now decipher the message
The highest number is 26 and the numbers from 1 to 26 are supposed to refer to the 26 alphabets in a particular order  like a,b,c.d,e....... or z,y,x,w,v etc

Group of 8 numbers-Rejoinder

Only one member-Shekar- could send an answer which was correct
The answer is that the 8th number is 25
This is arrived at as follows-
The average of the first 2 being 15.5 their total is 31.
The average of the next 3 being 64/3 their total is 64.
The average of all the 8 numbers being 20,their total is 160.
Thus the total of the last 3 should be 160-31-64=65
If the 6th number is denoted by 'x' the 7th and 8th numbers will be (x+4) and (x+7)
So their total will be x+(x+4)+(x+7)=3x+11.
Equating this to 65 we find x,the 6th number is (65-11)/3=18
Hence the 7th and 8th numbers are 22 and 25

Bookworm's travel

Here is a puzzle-
A bookworm eats from the first page of an encyclopedia to the last page.The bookworm eats in a straight line.The encyclopedia consists of ten 1000 page volumes and is sitting on a bookshelf in the usual order Not counting covers,title pages etc how many pages does the bookworm eat through?
Dont say it is easy- it eats through 10000 pages.
It actually eats through 8000 pages.Remember when the encyclopedia is in the correct order on the shelf,the first volume is on the left.so the first page is not on the extreme left.So also the last page is not at the extreme right.Thus only the middle 8 volumes consisting of 8000 pages has been travelled through..
