CALENDAR MAGIC

Question:

Which is the number in the centre of the square?

13

Question:

How many such lines can you draw?

Four such lines can be drawn.

Question:

Add the three numbers on each of these lines. What do you notice?

5 + 13 + 21 = 39

6 + 13 + 20 = 39

19 + 13 + 7 = 39

12 + 13 + 14 = 39

The sum of the numbers in each of the lines is 39.

Question:

Now look at the calendar of 2018. Also look for the present month and draw any similar square in your notebook. Does the magic work for these?

For the month of November 2018:

6 + 14 + 22 = 42

8 + 14 + 20 = 42

7 + 14 + 21 = 42

13 + 14 + 15 = 42

The sum is same i.e. 42. The magic works here as well.

Question:

Is this magic possible on a 10 × 10 number chart? Go to the chapter ‘Fun with Numbers’ and check.

Let’s check with a 10 x 10 number chart

Yes, the magic works in a 10 x 10 number chart also.

The cross lines- 1 + 12 + 23+ … + 89+ 100 = 505

and 10 + 19 + 28+ … + 82 + 91 = 505

As there is no middle line, we have to get average sum of both horizontal lines

5 + 15 + 25+ … + 95 and 6 + 16 + 26 + … 96 = 505

Average sum of both vertical lines

41 + 42 + 43 + … + 50 and 51 + 52 + 53 + … + 60 = 505.

Thus, the magic works here as well.
