Question

anil deposited 73000 in the bank if the currency notes given by him to the bank were of domination 10,50and 100 in the ratio 3:4:5 respectively.find the number of notes of each denomination

Answer 1

let the ratio be x
so no.of notes 3x,4x,5x
now given total is 73000
so
3x*10 + 4x*50+ 5x*100 =73000
x=73000/730=100
so 10 rs notes =3x=3*100=300
50rs notes= 4x=4*100=400
100rs notes= 5x=5*100=500

Answer 2

The number of notes in each denomination is

For domination 10 we have =3*100=300

Domination of 50=4*100=400

Domination of 100=5*100=500

Let the domination of each note be x

Then value of 10 rupees is 3*10*x=30x

Value of 50 rupees =4*50*x=200x

Value of 100 rupees is 5*100*x=500x

The total value is 73000

So we have:-

30x+200x+500x=73000

730x=73000 so x=100

So number of each notes:-

10 rupees note=3x=3*100=300

50 rupees note =4x=4*100=400

100 rupees note =5x=5*100=500
