Now, to find the solution.

According to question:

The number of nickels = .

The number of quarters =

So, the total number of coins:

He had 3 more quarters than nickels.

Thus,

.....(1)

Now, to get the solution:

Substituting the equation (1):

Subtracting both sides by 3 we get:

Dividing both sides by 2 we get:

The number of nickels = 6.

Now, substituting the value of in equation (1):

The number of quarters = 9.

Thus, there are 6 coins in nickels and 9 coins in quarters.
