In an alloy 83% is copper and remaining percentage is zinc and in another alloy 87% is copper and remaining percentage is zinc. The two alloys is mixed so that the new mixture must have 14% zinc. Find the ratio in which two alloys should be mixed to form the new mixture?

1 : 3

In first alloy, percentage of copper = 83%

In second alloy, percentage of copper = 87%

⇒ 1 ∶ 3 is the ratio in which the two mixture must mixed so that the new mixture has 86% copper.
