See if this magic works for other lines which have five numbers. What about five numbers on a slanting line? Try this trick with your family and friends. Can you find other magic patterns in the calendar?

उत्तर
The same pattern is followed for these five numbers also.
2 + 9 + 16 + 23 + 30 = 80
and 16 × 5 = 80
The numbers on the slanting lines are shown below.
29 +23 + 17 + 11 + 5 = 85 = 17 × 5
30 + 24 + 18 + 12 + 6 = 90 = 18 × 5
31 + 25 + 19 + 13 + 7 = 95 = 19 × 5
Yes. There is another magic pattern in the calendar.
8 + 9 + 10 + 11 + 12 + 13 + 14 = 77 = 11 × 7
Similar patterns can be seen in other rows too.
