Answer 1

Answer:

Step-by-step explanation:

Let, we know 1 ruppes =1000paisa

61ruppes=6100paisa

As the question 25P:20P:10P=3:7:9

Then,25*3x+20*7x+10*9x=6100

>75x+140x+90x=6100

>305x=6100

>X=6100/305=20

25*20=500

20*20=400

10*20=200

25*20*3=1500

20*20*7=2800

10*20*9=1800

Then sum of the 1500,2800,1800,is 6100 ,just to verification 1800 is the number of paise which we got adding the 61coin ,so number of 5 paisa coins=1800/10=90 answer
