Question

The ratio of weight of copper and zinc in brass is 13:7 find weight of zinc in brass utensil weighing 700 gm

Answer 1

Hey mate!!

Here's your answer

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 = 700/20

x = 35

Weight of copper = 13x = 13 × 35 = 455 grams

Weight of zinc = 7x = 7 × 35 = 245 grams

Hope it helped you.....Please mark me as brainliest.....

Answer 2

then 7x =700gm
x=100gm
then weight of copper =13×100gm
=1300gm
