1. Colour the supercells in the given table.

200 577 626 345 694 109 198
2. Colour the supercell in the table given below.

6828 670 9435 3780 3708 7308 8000 5583 52
3. Colour the subcells in the given table.

43 76 67 28 69 109 18

4. Write the numbers 11 to 20 in tabular form. Out of these 10 numbers, how many supercells and
subcells are possible?
5. Build any sixteen 5-digit numbers using digits 7, 0 and 4, when repetition is allowed. Fill the table
using those numbers such that only a coloured cell contains a number greater than all its neighbours.

40,007 77,400

6. Fill a table such that the cell having the second largest number is not a subcell but the second
smallest number is a supercell.
7. Can you fill a supercell table without repeating numbers such that there are no supercells?
8. This is a 4 by 4 magic square whose magic constant is 34. This magic square was 2 16 13 3
first found in India in Parshvanath Temple in Khajuraho. It is a pan magic square,
which is also called chautisa as the sum of rows, columns and diagonals is 34. 11 5 8 10
Colour the supercell number so that numbers in adjacent cells left and right, up 7 9 12 6
and down are less than the coloured number. Make a similar attempt to form a 14 4 1 15
subcell.
9. Colour the supercell and subcell of the following 5 by 5 magic square whose magical constant is 65.

11 24 7 20 3
4 12 25 8 16

17 5 13 21 9
10 18 1 14 22

23 6 19 2 15
10. This is a magic circle where the sum of the numbers on radii is
a magical constant.

27 + 15 + 3 + 24 = 69 = 28 + 5 + 11 + 25
Can you make a supercell for this magic circle? Please make a
colourful design of a magical supercell circle where the numbers
selected in the supercell should be considered on the adjoining
radius.
