Marcos quer pesar tr\u00eas ma\u00e7\u00e3s numa balan\u00e7a de dois pratos, mas ele disp\u00f5e apenas de um bloco de 200 gramas. Observando o equil\u00edbrio na balan\u00e7a, ele percebe que a ma\u00e7\u00e3 maior tem o mesmo peso que as outras duas ma\u00e7\u00e3s; o bloco e a ma\u00e7\u00e3 menor pesam tanto quanto as outras duas ma\u00e7\u00e3s; a ma\u00e7\u00e3 maior junto com a menor pesam tanto quanto o bloco. Qual \u00e9 o peso total das tr\u00eas ma\u00e7\u00e3s?<\/p>\n
a) 300 gramas
