X will be the no. Of 10 rs. Notes
Y will be the no. Of 20 rs. Notes
10x + 20y = 800
x + y = 50
So, 10x + 10y = 500
Now,
10x + 20y = 800
- 10x + 10y = 500
10y = 300
y = 30
x = 20
Y will be the no. Of 20 rs. Notes
10x + 20y = 800
x + y = 50
So, 10x + 10y = 500
Now,
10x + 20y = 800
- 10x + 10y = 500
10y = 300
y = 30
x = 20
