Answer 1

Answer:

Rs 20 denomination is 5 and Rs 10 denomination is 8

Step-by-step explanation:

total money Pranati has is rs 180.

1. let rs20 denomination be x
2. let rs10 denomination be x+3
3. multiply their values. i.e                                                                                                                          20*x=20x  and  10*x+3=10(x+3)=10x+30
4. now,  20x+10x+30=180
5. 30x+30=180
6. 30x=150
7. x=5
8. x+3=5+3=8
