Question

Two alloys contain silver and copper in the ratio of 2:3and3:4in what ratio the two alloys shoud be added together to get a new alloy having silver and copper in the ratio 1:2? find the percentage of gold in the alloy c​

Answer 1

Answer:

(Solution)

Alloy A = 300 and B = 300

Let 100 : 200 ( 1 : 2)

75 : 225 (1 : 3)

A = 100 × 2 : 200 × 2

75 × 3 : 225 × 3

425 : 1075

For % =1075/1500×100=215/3=71(2/3%)

Answer 2

Answer:

So, the new ratio of C is  1500:2100 and the percentage of gold in the alloy C is 58.33%.

Concept:

In chemistry, alloys are nothing more than the combination of two or more metals in varying quantities. For instance, an alloy of iron and carbon that typically also contains other metals like nickel and cobalt is called steel. Copper, zinc, and occasionally additional elements are combined to create brass.

Given:

1st ratio of silver = 2:3

2nd ratio of copper = 3:4

3rd ration after mixing to form new alloy = 1:2

Find:

We have to percentage of gold in the alloy C.

Solution:

Let alloy A = 300 and alloy B = 300

200 : 300 (2 : 3)

225: 300 (3 : 4)

A = 200 × 3 : 300 × 3

B = 225 × 4 : 300 × 4

C = 1500 : 2100

For % of gold alloy in C = $\frac{2100}{3600} * 100$

For % of gold alloy in C = 58.33%

The new ratio of C is  1500:2100 and the percentage of gold in the alloy C is 58.33%.
