CALENDAR MAGIC

Question:

Which is the number in the centre of the square?

Answer:

13

Question:

How many such lines can you draw?

Answer:

Four such lines can be drawn.

Question:

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

Answer:

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?

Answer:

For the month of November 2018:

Class 3 Maths Chapter 7 - 3

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.

Answer:

Class 3 Maths Chapter 7 - 4Let’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.
