### Examples of Number Puzzles and Games

Example 1:

Insert the eight four-digit numbers in the 4 × 4 grid, four reading across and four reading down.

{ 5 4 1 7, 8 6 2 1, 1 2 3 5 , 9 1 3 2, 6 1 9 3, 2 7 3 5, 3 7 5 1, 1 4 7 6, 6 5 2 8}

Solution:

Given set of numbers are { 5 4 1 7, 8 6 2 1, 1 2 3 5 , 9 1 3 2, 6 1 9 3, 2 7 3 5, 3 7 5 1, 1 4 7 6, 6 5 2 8}

At the first grid enter the numbers which have the common digit at the thousand’s place which are (6 1 9 3, 6 5 2 8).

Next enter the numbers wither from rows or columns.

After completing entering numbers in all the grids.

Check out once all numbers are numbers or not.

6 5 2 8
1 4 7 6
9 1 3 2
3 7 5 1

Example 2:

Find the value of A in the following image?

A

+ A

+ A

= B A

Solution:

In this case, A is a number its three times sum is a number and itself. Therefore, the sum of two A’s should be 0. Then the possibilities of A will be either 0 or 5.
If A = 0, then the total will be 0, so B = 0.
But is not possible. Because two different alphabets represent different numbers.
If A = 5, then
A + A + A = 5 + 5 + 5 = 1 5
So, B = 1, A = 5

Example 3:

Complete the magic square given below so that the sum of the numbers in each row or in each column or along each diagonal is fifteen.

Solution:

The total of each row or each column or diagonal is 15.

So, unfilled number in the second column is 15 – (1 + 5) = 15 – 6 = 9

Number at third row, third column is 15 – ( 6 + 5) = 15 – 11 = 4

Number at the first column, third row is 15 – (9 + 4) = 15 – 13 = 2

Number at first row, second column is 15 – (2 + 6) = 15 – 8 = 7

Number at first row, third coloumn is 15 – (6 + 1) = 15 – 7 = 8

Number at second row, third coloumn is 15 – (7 + 5) = 15 – 12 = 3
