Question

2) Alloy's of Brass proportion of Copper and Zink is 13: 7. Then how much
proportion of Zink in 700 gm Brass.

​

Answer 1

Step-by-step explanation:

Ratio of copper and zinc = 13:7

Total weight of brass = 700 g

Then, how much is the weight of copper and zinc.

Let, the equation be,

13x + 7x = 700

20x = 700

x = 700/20

x = 70/2

x = 35

Now substitute the value in the 13x and 7x

13x = 13 x 35

= 455.

7x = 7 x 35

= 245.

Therefore, the weight of copper is 455g and the weight of zinc is 245g.

Now, Check the answer whether it is correct or not

Just add the both values and check the sum of the values is 700 because the total weight of brass is 700.

455 + 245 = 700.

Hope this answer will help you
