You may GROUP coins, by placing one penny, one nickel and one dime in each group.


Each group is worth then 1 + 5 + 10 = 16 cents.


Having the total of 160 cents  MEANS  that you have  160%2F16 = 10  such groups.


From this point, there is only one step to get the 


ANSWER.  10 pennies, 10 nickels and 10 dimes.


OR

    x + 5x + 10x = 160

    16x          = 160

      x          = 160/16 = 10,

and you get the same answer.

Solved.
