Answer» Ratio of weights of copper and zinc in brass is 13 : 7 .Let proportionality constant is x then, weight of copper = 13x weight of zinc = 7x A/C to question, Given, weight of brass = 700 gm weight of copper in brass + weight of zinc in brass = 700 gm=> 13x + 7x = 700 => 20x = 700 => x = 35 hence, weight of copper in brass = 13 × 35 = 455 gm weight of zinc in brass = 7*35 = 245 g Hit like if you find it useful!

Answer»

Ratio of weights of copper and zinc in brass is 13 : 7 .Let proportionality constant is x then, weight of copper = 13x weight of zinc = 7x

A/C to question, Given, weight of brass = 700 gm weight of copper in brass + weight of zinc in brass = 700 gm=> 13x + 7x = 700 => 20x = 700 => x = 35

hence, weight of copper in brass = 13 × 35 = 455 gm weight of zinc in brass = 7*35 = 245 g
