Question

an alloy is to contain copper and zinc in the ratio 9:4. The zinc required to melt with 24 kg of copper is ?

Answer 1

Let the amount of zinc and copper jn that alloy ,4x and 9x. (Here x is the ratio constant)

So, according to the data mentioned in the question;

9x=24

x=24/9

So, the amount of zinc will be;

4x

= 4× 24/9

=10.6

So,the amount of zinc will be 10.6 kg (answer)

Answer 2

Step-by-step explanation:

Copper ⇒9x=24kg

⇒x= 9/24

Zinc ⇒4x=4× 9/24

answer 10 ×2/3kg
