Answer 1

he should mix in the ratio 3:2

Answer 2

The required proportion is 3:2.

Step-by-step explanation:

Since we have given that

Number of carats first qualities have = 10

Number of carats second qualities of gold have = 15

Number of carats in mixture = 12

So, Using "Mixture and allegations", we get that

First type       Second type

   10                     15

                12

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

 3             :                 2

Hence, the required proportion is 3:2.
