Let the number of notes of different denomination be x.
∴ 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
