Using positive integers from 1 to 64 inclusively, complete the grids
A to
D so that each of the columns, each of the rows
and each of the main diagonals in:
- Grid A totals 124.
- Grid B totals 128.
- Grid C totals 132.
- Grid D totals 136.
When the four grids are placed on top of each other, each of the 16 columns equal 130. For example, 61+14+03+52 = 130. Twenty
positive integers have already been displayed in the four grids in terms of the above diagram.
