Answer 1

Answer:

number of 20 are 60

Step-by-step explanation:

Given,

if jhons wallet contains some notes in the denominations of $10, $20,$50 in the ratio of 2:3:1

let the ratio of given denominations are 2x:3x:1x of 10,20,50

now the ratio is

10*2x : 20*3x : 50*1x

20x :60 x:50 x

if their total value is $2600

20x+60x+50x=2600

130x=2600

x=20

then 20x is 20*20=400

10 rupees notes are 400/10=40

60x is 60*20=1200

20 rupees notes are 1200/20=60

50x is 50*20=1000

50 rupees notes are 1000/50=20
