mass of 35 g. If the rate of gold is? 30,000.00 per 10 g, what
is the total cost of the ornaments?​

Answer 1

Answer:

Tricky Question. Wait I am solving

Step-by-step explanation:

This question is based upon unitary method .

First we will find the cost of 1 gram gold = 30,000÷10

= 3000 per gram

Now, the total mass of the ornaments = 35g(necklace) + 15g(ear rings)

= 50g

Now, We are near the answer.

Now , the cost of 50g gold= 3000×50

=150000

So , the total cost is 150000.
