Taxa nominal = 25,78% = (1+In)
taxa de juros real = ?    = (1+ Ir)
taxa inflação = 121,03% = (1+Ij)

fórmula => (1+In) = (1+ir).(1+Ij) logo:

(1+25,78/100) = (1+Ir).(1+121,03/100)

(1+0,2578) = (1+Ir).(1+1,2103)

(1+Ir) = 1,2578 / 2,2103

(1+Ir) = 0,569063023

Ir = 0,569063023 - 1

Ir= - 0,430936977 logo Ir= - 0,430936977 .100 = - 43,0937%.
