It would be 70 because 60+40+30=130 and to make 200 (have to make 200 and then we can divide every number by 2) we need 70 more.

Answer:58
Step-by-step explanation:
If 60% of the objects in the box are coins that means 40% of the objects are rings. And if 40% of the rings are gold then 40/100 * 40% = 16% of gold rings in the box
And for the coins if 30% of coins are silver meaning 70% of gold
60/100* 70% = 42% of gold coins
16% of gold rings + 42% of gold coins = 58% of gold particles in the box
