Answer 1

Answer:

100 : 50 : 10 = 2000 : 3000 : 5000

Step-by-step explanation:

2 : 3 : 5 = 100 : 50 : 10

Let us take the common term as x

2x : 3x : 5x = 3100 : 50 : 10

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

200x + 150x + 50x = 400000

400x = 400000

x = 400000

400

x = 1000

2x = 2000

3x = 3000

5x = 5000

${\huge{\fcolorbox{cyan}{lime}{\fcolorbox{yellow}{blue}{\sf{\color{yellow}{Answer:- }}}}}}</p><p>$

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
