Calendar Math’s Tricks

1) Saiqua’s Birthday Is on 02 April 1995. Draw a Saiqua’s Magic Square.

Since Saiqua’s birthday is on 02 April 1995.

We have DD = 02
MM = 04
CC = 19
YY = 95
Using the concept of Ramanujan’s Magic square, we have,

The numbers in the first row should be:
02, 04, 19, 95

The numbers in the second row should be:
95 + 1 = 96, 19 – 1 = 18, 04 – 3 = 01, 02 + 3 = 05

The numbers in the third row should be:
04 – 2 = 02, 02 + 2 = 4, 95 + 2 = 97, 19 – 2 = 17

The numbers in the fourth row should be:
19 + 1 = 20, 95 – 1 = 94, 02 + 1 = 03, 04 – 1 = 03

Therefore, the magic square is:

Magic Square 4 × 4
 
2)  Rina Created a Magic Square Based on Her Birthday, Which Is On 12-12-2010 As Given Below.

Find Out the Mistakes and Also Draw the Correct Magic Square.

Magic Square, created by Rina, was:

Magic Square 4 × 4

It is observed from the numbers in the first row are as follows:
DD, MM, CC, YY.
The numbers in the second row are as follows:
CC – 1, YY + 1, MM – 3, DD + 3, whereas the correct order is
YY + 1. CC – 1, MM – 3, DD + 3.

The numbers in the third row are as follows:
MM – 2, DD + 2, CC – 2, YY + 2, whereas the correct order is
MM – 2, DD + 2, YY + 2, CC – 2.

The numbers in the fourth row are as follows:
YY – 1, CC + 1, DD + 1, MM – 1, whereas the correct order is
CC + 1, YY – 1, DD + 1, MM – 1

Therefore, it is observed that Rina has interchanged the position of CC and YY from the second row to the fourth row.

The correct magic square is shown below:

3) Help Sharukh to complete the Magic Square for His Pet Dog Tommy’s Birthday.
 
Magic Square 4 × 4

From the first row, it is observed that:
DD = 08
MM = 10
CC = 19
YY = 90

The numbers in the second row should be as follows:
YY + 1. CC – 1, MM – 3, DD + 3, that is,

91, 18, 07, 11. Therefore, the missing numbers in the second row are 91 and 11.

The numbers in the third row should be as follows:
MM – 2, DD + 2, YY + 2, CC – 2, that is,
08, 10, 92, 17. Therefore, the missing numbers in the third row are 08 and 92.

The numbers in the fourth row should be as follows:
CC + 1, YY – 1, DD + 1, MM – 1, that is
20, 89, 09, 09. Therefore, the missing numbers in the third row are 89 and 09.

The complete magic box is shown below.
