A goldsmith mixes silver and gold in the ratio 3:7 .Find the amount of gold and silver used in a chain weighing 90 grams​

Answer 1

Answer:

63g & 27g, respectively.

Step-by-step explanation:

Let us say that the amount of silver is 3x.

And, the amount of gold is 7x.

Then, according to the question,

3x + 7x = 90

10x = 90

x = 9

So, amount of silver = 3 × 9g = 27g

Amount of gold = 7 × 9g = 63g
