C=capital C=125000
a) juros simples taxa=2,5% => i=taxa unitaria=2,5/100=0,025; n=periodos=4meses
    J=C*i*n => J=125000*0,025*4 => J=125000*0,1 => J=12500
b) juros compostos taxa=3%am =>i=3/100=0,03; n=3meses
    J=M-C;     M=C(1+i)^n;
M=125000(1+0,03)^3 => M+125000(1,03)^3 => M=125000*1,092727
M=136590,88 => J=136590,88-125000,00 =>J=11590,88
