Question

2 points
In an alloy of 80 gm , copper is 60 gm and the remaning is zinc , the ratio copper to zinc is ....​

Answer 1

Answer :-

The ratio of copper to zinc is 3 : 1.

Step-by-step explanation:

To Find :-

• The ratio of copper and zinc.

★ Solution

Given that,

• Total quantity of alloy = 80gm
• Total quantity of copper in alloy = 60gm.

∴ The quantity of zinc in alloy :-

⇒ Total quantity of alloy = quantity of [copper - zinc]

⇒ 80gm - 60gm

⇒ 20gm = quantity of zinc

Now, According the question,

• The ratio of copper to zinc

⇒ 60 : 20

⇒ 6 : 2

⇒ 3 : 1

Hence,

The ratio of copper to zinc is 3 : 1.
