Answer:

The weight of pure gold in 258 g rams of 18- karat gold is 193.5 grams.

Step-by-step explanation:

The pure percentage in the gold = 75%

The weight of the gold purchased = 258 g

Now, here the pure gold percentage is 75% of 258 g

75% of 258 grams = \frac{75}{100}  \times 258

or,  \frac{3}{4}  \times 258  = 193.5

⇒75% of 258 grams  = 193.5 grams

Hence, the weight of pure gold in 258 g rams of 18- karat gold is 193.5 grams.
