Answer 1

Step-by-step explanation:

Let us take the no. 100 rs notes be 2x, the no. of 50 rs notes be 3x and the no. of 10 rs notes be 5x.

Let us now form an equation,

2x+3x+4x=3400.000

9x=3400

x=3400/9

x=377.7

• No. of 100 rs notes=2x= 2×377.7=755.4 i.e 755 notes
• No. of 50 rs notes=3x=3×377.7=1133.1 i.e 1131 notes
• No. of 10 rs notes = 5x=5×377.7=1888.5 i.e 1888 notes

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
