This is just ...

    ... spelling math I think?

- one one one is 9 letters
- four four four is 12 letters
- seven seven seven is 15 letters

so eight eight eight  Would be 15 letters.

Well, the (perhaps too) obvious answer is that

the RHS increases by 3 for every 333 increase on the LHS. Then 888=16

18

Ignore the triple numbers. It is the same like 9,12,15,... so the answer must be 18

  • $\begingroup$ Are you sure? As in such a case 09, 12, 15, __ could have been the question then, instead of an equation based question. $\endgroup$ – Mea Culpa Nay Nov 25 '17 at 2:59

For 888 it is

24

As,

888 = 111 + 777 or 2 × 444. That is either 09 + 15 or 2 x 12 which is 24.

    $\begingroup$ If that were true, then given 111 = 09, 444 = 36. $\endgroup$ – Sneftel Nov 24 '17 at 18:54
