I conducted a mega World Record event at Madurai with the participation of 1,729 students of the Mannar Thirumalai Nayakar college in Madurai making 17,290 individual date-of-birth Magic Squares to the date of birth of the Great Indian Mathematician Srinivasa Ramanujan (22nd December 1887).

This mega World Record event the was certified by Kalam’s World Records based in Chennai.

This is the most fitting tribute to the Great Indian mathematician Srinivasa Ramanujan on his 135th birth anniversary celebrated worldwide.

Here is a video which covers the event (audio is in native language Tamil though).

]]>This is a Unique Puzzle that makes magic squares for his date of Birth on 22-12-1887 and for his **102nd Remembarance day, today(26-4-2022)**

On Left side we are having a brown color magic square for 22-12-1887 giving a total of 139 in all vertical, Horizontal and both diagonals.

On the right side we are having a light green color magic square for 26-4-2022 giving a total of 174 in all vertical, Horizontal and both diagonals.

And the balance squares are filled with compensatory numbers.

**The final form is a 9 x 9 Magic square is giving a total of 313 in all vertical, Horizontal and both diagonals. **

Some of my friends asked about the procedure for doing the above puuzzle.

Just look into the pattern closely for two or three times.

All yellow numbers are written on clockwise and the blue squares are filled with anti clockwise.

Now check the total of two blue squares and in between yellow square.

Adjust some the numbers in the begining to come at the total correctly.

**ENHANCING THE TOTAL TO THE REQUIRED NUMBER**:

Now let the required total be 2025.

Deduct 369 from the 2025, you will get 1656

Since the total 369 is the addition of 3 squares, divide 1656 by 3, you will get 552.

Now add 552 in all the squares. the total of two blue squares and in between yellow square. you will get 2025

The format 1 to 210 will give a total of 369 and you have added 3 x 552, you will get 369 + 1656 = 2025.

]]>All numbers from 1 to 1000 are utilised in this puzzle and any three continuous squares ( two brown squares and one Blue square in between will give the same total of 1752 at any given point.

I thank the Almighty for giving me the idea, conducted me, guided me to complete the NEW BIGGEST CIRCULAR NUMBER PUZZLE.

]]>The entire world is celebrating the 135th Birth year of the famous Indian Mathematician Srinivasa Ramanaujan. On this occassion we proudly submit a new idea/ puzzle that gives a total of 135

In the above puzzle, count any three successive **(two blue squares and one brown square in between)** throughout the round, you will get 135

]]>It is a puzzle with seven sides and each meeting point and the middle of the line are placed with some numbers. The numbers are so arranged that any two numbers on two continuous points and one middle number betwwen them will always give a total of 26.

As a puzzle lover it attracted me to expand this puzzle in a bigger way.

In my first attempt after so many trail and errors I made my first puzzle with numbers 1 to 22 with total of 40

Then I expanded it from 1 to 46 with a total of 82

Now I made a Biggest one successfully with all numbers from 1 to 210 with a total of 369, and it is in a zig zag form with the same concept.

Hope you can enjoy and get some idea and enjoy Maths in a easy way.

Best of luck, kindly go through my website www.jollymaths.com

]]>1) Let the given date is 14-7-2021.

2) The formula is [ K + { (M-2) x 2.6 – 0.2 } + C/4 + D/4 +D-2C] divided by 7

3) Where K is the date M is the month C is the century D is the last two digit of the year

4) [ 14 + { (7-2) x 2.6 – 0.2} + 20/4 + 21/4 + 21 – 40 }] divided by 7

if M – 2 is zero or -1 ( Feb or Jan) , less one from the year ( D ) and add 12 months to month M.

Drop all the residuals/fractions in all cases and take the whole number only

5) [ 14 + 12.8 + 5 + 5 + 21 – 40] divided by 7

6) {14 + 12 + 5 + 5 + 21 – 40) divided by 7

7) 17 / 7 = 2 and 3/7

If the reminder comes ZERO, it is SUNDAY. 1/7 means MONDAY, 2/7 means Tuesday, 3/7 means WEDNESDAY, 4/7 means THURSDAY, 5/7 means FRIDAY AND 6/7 means SATURDAY.

Hence 14-7-2021 is Wednesday .

9) Try for other dates also.
