Question

. The ratio of weights of copper and zinc is 13.: 7. Find the weight of the zinc in a brass utensil weight is 500g,​

Answer 1

Answer:

Let proportionality constant be 'x'

then, weight of copper =13x

and weight of zinc =7x

As per the question

Weight of brass =500 gm

Weight of copper in brass + Weight of zinc in brass =700 gm

⇒13x+7x=500

⇒20x=500

⇒x=25

Hence, Weight of copper in brass =13×25=325 gm

Weight of zinc in brass =7×25=175 gm
