The ratio of the notes is : 2 : 3 : 5
Let her have 2 * N number of Rs 100 notes, 3 * N number of Rs 50 notes, and 5 * N number of Rs 10 notes respectively.
Then the total value of the currency notes will be:
2 N * Rs 100 + 3 N * Rs 50 + 5 N * Rs 10 = Rs 4, 00, 000
=> 200 N + 150 N + 50 N = Rs 4, 00, 000
=> 400 N = Rs 4, 00, 000
=> N = 1, 000
Hence, There are 2N = 2,000 notes of Rs 100 , 3N = 3,000 notes of Rs 50 and finally , 5 N = 5, 000 notes of Rs 10..

Answer:
Let 100 rupee be 100x
50 rupee be50x
10 rupee be 10x
Now,
Value of 100 rupee 50 rupee and 10 rupee be 2*100x ,3*50x ,5*10x
= 200x+150x+50x= 400000
400x=400000
X= 1000
No of 100 rupee notes=200*1000=200000
No of 50 rupee notes =150*1000=150000
No of 10 rupee coin = 50*1000=50000
