Let number of 20 Rs notes be x

according to question

number of 5 Rs notes = 2x

number of 50 Rs notes =

5

x

then 5(2x)+20(x)+

5

x(50)

=200

10x+20x+10x=200

40x = 200

[x=5]

then number of 5 Rs notes = 10

then number of 20 Rs notes = 5

then number of 50 Rs notes = 1

Answer 2

Answer:

Total no.of Rs 5 notes are =10,

Rs 20 notes = 5

Rs 50 notes = 1

Step-by-step explanation:

let the number of Rs 20 notes be x.

Then number of Rs 5 notes will be 2x.

Then Rs 50 notes will be x/5.

Now,

• 20x + 5*2x + 50* x/5 = 200
• 20x + 10x + 10x = 200
• 40x = 200
• x = 5

Total no.of Rs 5 notes are =10,

Rs 20 notes = 5

Rs 50 notes = 1
