Step-by-step explanation:

Let he has x notes of 50.

Rupees of notes of 50 = 50x

notes of 20 = 5x/3

rupees of notes of 20= 100x/3

notes of 10= 25-x-5x/3

75-8x/3

rupees of notes of 10= 10(75-8x)/3

rupees of notes of 10= 590- 50x- 100x/3

= 1770-150x-100x/3 = 10(75-8x)/3

= 177-15x-10x/3= 75-8x/3

= 177-25x=75-8x

= -17x = -102

= x = 6

So, notes of 50 = x = 6

notes of 20 = 5x/3 = 10

notes of 10 = 25-10-6=9
