Alloy A weighs 18 g

Alloy B weighs 6 g

Step-by-step explanation:

Let the weight of Alloy A be "x" g and Alloy B be "y" g.

It is given that Alloy A is composed of 3 parts gold and 1 part silver and Alloy B is composed of 1 part good and 3 parts silver.

The total gold is given by,

= = 15 g

The total silver is given by,

= = 9 g

adding both the equations we get,

and subtracting we get,

Thus, by solving we get,

x=18 and y=6.
