Answer 1

Answer:

Let a number of notes are 2x, 3x and 5x.

According to question, 100 x 2x + 50 x 3x + 10 x 5x =4,00,000

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

400x=4,00,000⇒ 400x=4,00,000

{400x}{400}=\frac{400000}{400}⇒

400

400x

=

400

400000

[Dividing both sides by 400]

x = 1000

Hence, number of denominations of ` 100 notes = 2 x 1000 = 2000

Number of denominations of ` 50 notes = 3 x 1000 = 3000
