Remark
Just to make 2 answers possible, I will add how I think this problem should be done. Start with the lone tile on the right. There is only 1 tile in that group. Make a table
Table
Number in 1 group Name Groups Total
1 units 1 1 * 1 = 1
10 tens 3 3 * 10 = 30
10*10 = 100 hundreds 4 4 *100 = 400
Total 431
The answer is 431
