.
Let  N be the number of nickels.

Then the number of dimes is (N+5), and the number of quarters is 4N


    (in English, "There are 3 times more quarters than nickels" means that 
                 there are 4 times as many quarters as nickels  (!!!) ).


So, your equation is

5N + 10(N+5) + 25*(4N) = 1040   cents.


5N + 10N + 50 + 100N = 1040  ====>

115N = 1040-50 = 990  ====>  N = 990%2F115  is not an integer.


Which means that your condition/problem/formulation is  DEFECTIVE.



     The cause is that you don't know that in English

     "There are 3 times more quarters than nickels" means that "there are 4 times as many quarters as nickels".


Next time be more attentive and more accurate.
