Answer:
100
Step-by-step explanation:
Total = ₹1600
Notes: ₹10, ₹20
Proportion: 2:3
As per proportion and the sum we have:
- 2x*10+3x*20=1600
- 20x+60x=1600
- 80x=1600
- x=1600/80
- x=20
As per value of x we found that:
- 2x=40 => Number of ₹10 notes is 40, sum= ₹400
- 3x=60 => Number of ₹20 notes is 60, sum= ₹1200
- Number of notes: 40+60=100
Answer: bag contains 100 notes
