The answer is  6, 10, 9
===========================
let number of Rs 50 notes = 3 N
number of Rs 20 notes = 5 N
The number of Rs 10 notes = 25  - 3 N - 5 N = 25 - 8 N

Total Value of the notes:
  Rs 590 =  3 N * 50 + 5N * 20 + (25 - 8 N) * 10
             = 170 N + 250

  N = 340 / 170  = 2

So  there are 6 notes of Rs 50,  10 notes of Rs 20 and  9 notes of Rs 10.
