Answer:
Let the no of notes be 2x, 3x,4x
from Rs 2000 = Rs 2000 × 2x = 4000x
from Rs 500 = Rs 500 × 3x = 1500x
from Rs 100 = Rs 100 × 4x = 400x
total amount of = 11,800
withdrawal.
ATQ ; Rs 4000x + 1500x + 400x =11,800
5,900x = 11, 800
x = 11,800/5,900
x = 2
hence : 2x = 2(2)= 4
3x =3 (2)=6
4x. = 4(2) = 8
Therefore she has notes of denomination of 4, 6, 8 of Rs 2000, Rs 500 , Rs 100.
