Extraemos los datos del problema:
- Capital Inicial → C₀ = S/.25000
- Interés bimestral → i = 8 % = 0.08
- Periodos → n = 3
Capital Inicial Bimestre → C = S/.25000
Tasa de interés bimestral:
I = C×i
I = S/.25000 × 0.08
I = S/.2000
Monto final:
M = C + I
M = S/.25000 + S/.2000
M = S/.27000
Variación Porcentual:
% = (M - C₀) / C₀
% = ( 27000 - 25000) / 25000
% = 8
<h2>Bimestre 2:</h2>Capital Inicial Bimestre → C = S/.27000
Tasa de interés bimestral:
I = C×i
I = S/.27000 × 0.08
I = S/.2160
Monto final:
M = C + I
M = S/.27000 + S/.2160
M = S/.29160
Variación Porcentual:
% = (M - C₀) / C₀
% = ( 29160 - 25000) / 25000
% = 16.64
<h2>Bimestre 3:</h2>Capital Inicial Bimestre → C = S/.29160
Tasa de interés bimestral:
I = C×i
I = S/.29160 × 0.08
I = S/.2332.8
Monto final:
M = C + I
M = S/.29160 + S/.2332.8
M = S/ 31492.8
Variación Porcentual:
% = (M - C₀) / C₀
% = ( 31492.8 - 25000) / 25000
% = 25.97
