Step-by-step explanation:
Total sum of rupees = Rs. 550
Let the no. of Rs . 10 notes be = x
No. of Rs . 50 notes = x - 1
Amount of Rs. 10 notes = 10( x )
= 10x
Amount of Rs. 50 notes = 50(x - 1)
= 50x - 50
According to question
10x + 50x - 50 = 550
60 x = 600
x = 10
So , number of 10 rupees notes = 10
number of 50 rupees notes = 9
