Question

Gastei 1/3 do salario com aluguel, 1/4 com comida ,1/5 com outras contas e 1/6 com remedios. Ainda me sobraram 255 reais . Qual e o meu salário?

Answer 1

X = Sálário

x - (1/3)x - (1/4)x - (1/6)x = 255

x - (1/4)x - (1/6)x - (1/3)x = 255

(4/4)x - (1/4)x - (1/6)x - (2/6)x = 255

(3/4)x - (3/6)x = 255

(3/4)x - (1/2)x = 255

(3/4)x - (2/4)x = 255

(1/4)x = 255

x = 4.255

x = 1020

Resposta: R$ 1.020,00
