NUMBER PYRAMID

                  In a number pyramid, the number in each space is                                    9

                  the sum of the two numbers below it.                                             5     4

                     Start with a space, which has two filled adjoining
                    spaces below it.                                                           3      2     2
                     Here  blue circle is the sum of two  green circles.                    2      1     1      1
                    Therefore, blue circle is 2 + 1 = 3.
                      We can get the remaining numbers by following the same pattern.




                            NUMBER GRID


                  In a number grid each grid is replaced by the value of its result. Let us start filling
                  the numbers in the grid by solving each grid.
                     We usually start with the number at the centre. Here, it is 30.



                                            10 less
                                           than 30



                                                       1 more
                                1 less                  than
                              than 30       10+20        30                              30




                                          10 more
                                          than 30


                      Now, fill the remaining places in the grid according to the instruction given in
                    each box.




                            SECRET MESSAGE: DECODING

                  Decoding  is  the  process  of  converting  a  hidden  message  to  a  meaningful

                  text. The hidden message or secret message can be in the form of a symbol,

                  number, picture, letter, or a pattern.

                  For example,  if                1             2             3   then  the  secret  message

                                         will be decoded as 132112.
