Answer 2

There were 8 more silver coins than gold coins in the jar.

Explanation:

Given that:

Total coins in the jar = 80 coins

Gold coins = 25% of total coins

Number of gold coins =
`(25)/(100)*80`

Number of gold coins = 20

Silver coins = 35% of total

Number of silver coins =
`(35)/(100)*80`

Number of silver coins = 28

Copper coins = 40% of total

Number of copper coins =
`(40)/(100)*80=32`

Difference between silver and gold coins = No. of silver coins - No. of gold coins

Difference = 28-20 = 8

Hence,

There were 8 more silver coins than gold coins in the jar.
