Answer 1

Step-by-step explanation:

The ratio of copper and zinc in a 63 kg alloy is 4: 3. Some amount of copper is extracted from the alloy, and the ratio becomes 10: 9. How much copper is extracted? x = 36-30 = 6 kg.

Answer 2

Answer:

mark me as brainlist

Step-by-step explanation:

In 63 kg of alloy amount of copper would be 36 kg and zinc would be 27 kg

Amount of copper = 63 *4 /(4+3) =36 kg

Amount of zinc = 63 *3 /(4+3) =27 kg

If x kg copper extracted and ratio will 10:9

So,

(36-x)/27 = 10/9

Solving it x = 6

By extracting 6 kg copper it turns out to be 30 kg copper and 27 kg zinc
