Answer:

3 ring

Step-by-step explanation:

Total number of jewelry = 10

number of necklace = 1÷2 * 10 = 5

number of bracelets = 2÷5 * 5 = 2

Total of both = 5+ 2= 7

remainder = Total jewelry - sum of necklace and bracelet

remainder = 10 - 7

= 3

therefore there are three rings in the jewelry box
