--------------------------
Last Year | 100 | 10
This Year | 105 | 12.6

The amount saved this year as a percent of the amount saved last year = (12.6/10)*100
=>126%

Let us assume that Carlos' annual earnings last year = C
Then Carlos' savings last year = 10% of C = 0.1C
Carlos' earnings this year = 1.05C
Carlos' savings this year = 1.05C * 0.12 = 0.126C, which means the amount saved this year was 126% of the amount saved last year.

The correct answer is C.

Let n = the amount saved last year. The amount saved this year, as a percentage of what was saved last year, is:

(1.05n * 0.12)/(0.1n) = 1.05 * 1.2 = 1.26 = 126%
