Você tinha R$800,00 pois se 1/4 são R$200,00 3/4 seriam R$600,00 e somando R$600,00 + R$200,00 = R$800,00 

Mendelevium: 3/4 são 75%, se você gastou 75% e sobrou 200 que são 25% é só fazer 200 . 4 = 800

Mendelevium: x - 3x/4 = 200 4x - 3x = 800 x = 800

                                               Resposta final
 A sua quantia era de R$ 800,00
                                                Porque?
1 / 4 de X = 200 = 200 X 4 = 800
2 / 4 de X = 200 = 200 X 2 = 400 
3 / 4 de X = 200 = 200 X 3 = 600
600 + 200 = X 
X = 800

Obs: o 1 / 4 tambem é a resposta correta. Fiz de 2 jeitos para qualquer um entender.
