What number is shown here? a) 71 b) 431 c) 710 d) 4,031

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
