Question

Answer 1

Step-by-step explanation:

Let the no. of notes be

2x, 3x, 4x

100(2x) + 50(3x) + 10(5x)

According to the question,

100(2x) + 50(3x) + 10(5x) = 4,00,000

200x + 150x + 50x = 4,00,000

400x = 4,00,000

x = 4,00,000/400

x = 1000

Ans = Notes of each denomination she have =

100 = 2x= 2 × 1000 = 2000

50 = 3x = 3 × 1000 = 3000

10 = 5x = 5 × 1000 = 5000
