ncert-solutions-for-class-3-mathematics-chapter-7-time-goes-on-26
Number 14 is in the centre of the square. On joining three numbers in a line we have.
On adding these numbers, we get
6 + 14 + 22 = 42
7 + 14 + 21 = 42
8 + 14 + 20 = 42
13 + 14 + 15 = 42
The total of each line is the same. Yes, the magic also works here.

5.Is this magic possible on a 10 x 10 number chart. Go to the Chapter ‘Fun with Numbers’ and check.

ncert-solutions-for-class-3-mathematics-chapter-7-time-goes-on-9
In the first square we have
31 + 22 + 13 = 66
32 +’22 + 12 = 66
33 + 22 + 11 = 66
21 + 22 + 23 = 66
Therefore, magic works.
In the second square, we have
61 + 52 + 43 + 34 + 25 = 215
63 + 53 + 43 + 33 + 23 = 215
65 + 54 + 43 + 32 + 21 = 215
41 + 24 + 43 + 44 + 45 = 215
Therefore, magic also works here.
