Let the numbers in the ratio be 13x and 7x
It means weight of copper = 13x
Weight of zinc = 7x
Given, weight of brass = 700 gm
According to the question,
13x + 7x = 700
20x = 700
x =
x = 35
Weight of copper = 13x = 13 × 35 = 455 grams
Weight of zinc = 7x = 7 × 35 = 245 grams

Heya mate, Here is ur answer
Then weight of copper metal in brass alloy =13 x
weight of zinc metal in brass alloy=7 x
Total weight of alloy(utensil) =13x+7x
=20 x
A/Q
Weight of brass utensil=700 gm
So,
20x=700
x=700/20
x=35
So, weight of copper in brass utensil=13×35
=455
Weight of zinc in utensil=7×35
=245
============================
