Answer 2

Hi friend

Your answer

--------------------

In an alloy,

Copper : Zinc = 7 : 3

Weight of Copper = 12.6 grams

Now,

---------

Total parts= (7 + 3) = 10

Let the weight of the alloy be x.

Then,

7/10 × x = 12.6

=> x = (12.6 × 10)/7

=> x = 18 grams

∴ Weight of the alloy is 18 grams.
