notes of each denomination does she have?
​

Answer 1

Answer:

Let the number of 100 rupees note=2x

Then, the number of 50 rupees note=3x

Then, the number of 10 rupees note=5x

We are given,

100 (2x)+50(3x)+10(5x)=400000

200x+150x+50x=400000

400x=400000

x=1000

So, the number of 100 rupees note=2000

The number of 50 rupees note=3000

The number of 10 rupees note=5000

Answer 2

Let the numbers of notes of ₹100, ₹50 and ₹10 be 2x, 3x and 5x respectively.

Value of ₹100 = 2x × 100 = 200x

Value of ₹50 = 3x × 50 = 150x

Value of ₹10 = 5x × 10 = 50x According to the question,

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

⇒ 400x = 4,00,000

⇒ x = 400000/400

⇒ x = 1000

Numbers of ₹100 notes = 2x = 2000

Numbers of ₹50 notes = 3x = 3000

Numbers of ₹10 notes = 5x = 5000
