  1. Answer:

    The ratio of weight of copper and zinc in brass is 13 : 7. Let the weight of the copper be 13x. Weight of zinc be 7x. Hence, the weight of zinc in a brass utensil is 245 gm.

  2. Explanation:–

    Let proportionality constant be ‘x’

    then, weight of copper = 13x

    and weight of zinc = 7x

    As per the question

    Weight of brass = 1400 gm

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

    ⇒13x + 7x = 1400

    ⇒20x = 1400

    ⇒x = 70

    Hence, Weight of copper in brass = 13 × 70 = 910 gm

    Weight of zinc in brass = 7 × 70 = 490 gm

    Answer:

    Weight of copper in brass = 910 gm

    Weight of zinc in brass = 490 gm
