total value = 1600
ratio of ₹10 and ₹20 coins= 2:3
from question...
2x×10+3x×20= 1600
20x+60x= 1600
80x= 1600
x= 1600/80= 20
total number of notes= 20×(2+3)= 20×5= 100.

Answer:

100

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
