Starting from 1, find the sum of the first SEVEN whole numbers that do not contain a 3, 5 or 7 as part of their number, or are not multiples of 3, 5 or 7.

The 7puzzle Challenge

The playing board of the 7puzzle game is a 7-by-7 grid of 49 different numbers, ranging from up to 84.

Can you arrive at 58 by inserting 4, 6, 8 and 10 into the gaps on each line?
