We call a number odd looking if all of its digits are odd.

(111, 113, 115, 117, 119, 131, 133, 135, 137, 139, 151, 153, 155, 157, 159, 171, 173, 175, 177, 179, 191, 193, 195, 197, 199, 311, 313, 315, 317, 319, 331, 333, 335, 337, 339, 351, 353, 355, 357, 359, 371, 373, 375, 377, 379, 391, 393, 395, 397, 399, 511, 513, 515, 517, 519, 531, 533, 535, 537, 539, 551, 553, 555, 557, 559, 571, 573, 575, 577, 579, 591, 593, 595, 597, 599, 711, 713, 715, 717, 719, 731, 733, 735, 737, 739, 751, 753, 755, 757, 759, 771, 773, 775, 777, 779, 791, 793, 795, 797, 799, 911, 913, 915, 917, 919, 931, 933, 935, 937, 939, 951, 953, 955, 957, 959, 971, 973, 975, 977, 979, 991, 993, 995, 997, 999) = 125 such numbers.

Thx, guest....a faster way

5  integers  in  each  of the hundreds, tens and ones place are odd.....

So  5 * 5 * 5   =   125
