Let the no of 10rs and 20rs notes be 2x and 3x
Total money=1600
10(2x)+20(3x)=1600
20x+60x=1600
80x=1600
x=20
So no of 10rs notes=40
And 20rs notes =60
So total no of notes are =100
Total money=1600
10(2x)+20(3x)=1600
20x+60x=1600
80x=1600
x=20
So no of 10rs notes=40
And 20rs notes =60
So total no of notes are =100

Answer:
100 Notes
Step-by-step explanation:
Let the number of Rs. 10 notes =2x
Let the number of Rs. 20 notes =3x
Value of Rs. 10 notes =2x×10=Rs.20x
Value of Rs. 20 notes =3x×20=Rs.60x
Total money in the bag =Rs.1600
So,
20x+60x=1600
80x=1600
x=
80
1600
x=20
The number of Rs. 10 notes =2x=40
the number of Rs. 20 notes =3x=60
Total number of notes =40+60=100
