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
