As in the pictures you can see the natural multiplication process of two numbers. Both the pictures show multiplication of the same numbers but in different number systems. Find the numbers. Hint: The numbers in the first picture are in decimal number system. Note: Here same numbers means that the digits of the two numbers are same. For any other queries post comment below.

This is an array of integers and operations. Each connected row or column with operations performed result in the value 10. The operations have their order of priority. The blank spaces can be filled up by digits from 0-9. NO repetition of digits  in the same row or column. Above shown is a complete row. Some spaces are already filled with 2 to make the solution unique. Fill the digits.

Solution to the encoded text problem . iwu vlgTc nmeah kfp rzeboe tyqr xdh duoj oeo It contains 36 letters . As in the given hint you can use matrix encryption algorithm make it a 6 x 6 matrix.   i   w   u   v   l   g T   c   n   m  e   a h   k   f    p   r    z e   b   o   e   t    y q   r   x   d    h   d  u   o   j   o    e    o Now take the transpose of the matrix. i    T   h   e    q   u w  c   k    b    r   o u   n   f    o   x    j v   m  p   e    d   o l    e   r    t     h   e g   a   z ...

There is given below some encoded text. It is encoded using matrix cypher algorithm. The decoded message is simple and well known. Try it for yourself. iwu vlgTc nmeah kfp rzeboe tyqr xdh duoj oeo Note:The letters are only scrambled. The entire message contains only letters from this code.   click here for solution

This is the solution to the modified sudoku posted on 13/2/2012

Each small square should contain a number. Each 3 X 3 square should contain numbers from 1 to 9. Each row and column should not have any repetitions. click here for solution.

This is the solution to  find the letter. The numbers corresponding to the convex objects are parallelogram = 1 rectangle = 2 circle = 3 triangle = 4 overlapping area operation is addition. The encryption algorithm for conversion of numbers to letters is n*7(mod26) so the answer is (2+3+4)*7 (mod26)= 11 ~ k in alphabet

This picture contains letters corresponding to numbers. eg. a-1,b-2 like that. Each convex object correspond to a distinct integer. At the overlapping region some operation happens between the integers. This problem uses modular arithmetic. Find the letter at "?" . Click here for solution.
