is Rs 4,00,000. How many notes of each denominations does she have ​

Answer 1

Step-by-step explanation:

Let the number of notes of different denomination be x.

∴ Numbers of Rs100 notes, 50 notes and Rs10 notes will be 2x,3x and 5x respectively.

Amount of 100 Rs notes ⇒Rs100×2x=200x

Amount of 50 Rs notes ⇒Rs50×3x=150x

Amount of 10 Rs notes ⇒Rs10×5x=50x

As per the question

Total amount =400000

200x+150x+50x=400000

400x=400000,x=1000

No of Rs 100 notes =2x=2×1000=2000

No of Rs 50 notes =3x=3×1000=3000

No of Rs 10 notes =5x=5×1000=5000

Answer 2

Answer:

Here is ur solution :-

Step-b-step explanation:

Let no. of notes of Rs. 100 = 2x

Let no. of notes of Rs. 50 = 3x

Let no. of notes of Rs. 10 = us

According to question :-

100×2x+50×3x+10x × 5x = 4,00,000

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

400x = 4,00,000

x = 4,00,000÷400

x = 1000

So, Rs.100 notes = 2x

= 2×100

= 2000 notes

Rs. 50 notes =3x

=3×1000

= 3000 notes

Rs. 10 notes = 5x

= 5×1000

= 5000 notes
