Answer:
Numbers of Rs100 notes, 50 notes and Rs10 notes will be 2x,3x and 5x respectively.
Amount of 100 Rs notes ⇒Rs100×2x=200x
Amount of 50 Rs notes ⇒Rs50×3x=150x
Amount of 10 Rs notes ⇒Rs10×5x=50x
As per the question
Total amount =400000
200x+150x+50x=400000
400x=400000,x=1000
No of Rs 100 notes =2x=2×1000=2000
No of Rs 50 notes =3x=3×1000=3000
No of Rs 10 notes =5x=5×1000=5000

Answer:
Step-by-step explanation:
denomination of 20rs note=20×3x=60x
Denomination of 50rs notes =50×4x=200x
Denomination of 100rs notes =100×5x=500x
The sum of 500x,200x,60x=68400
500x+200x+60x=68400
760x=68400
X=68400/760
X=90
Then put the value of X
60×90=5400
200×90=18000
500×90=45000
