Question

A 2000 rupees note was changed to 100 and 50

rupees notes, total 28 notes in all. How many 100

and how many 50?​

Answer 1

Let the number of
100₹ notes be x ====> 100(x)
Then
50₹ notes will be 28-x===> 50(28-x)

Now

Total amount = 2000₹

100(x) + 50(28-x) = 2000
100x + 1400 - 50x = 2000
50x = 2000-1400
50x = 600
x = 12

100₹ notes = 12 notes
50₹ notes = (28-12) = 16 notes

Answer 2

Answer:

there will be 12 100notes and 16 50 notes

Step-by-step explanation:

let x will be no of 100/- notes and y will be no of 50/- notes

2000=100x+50y=> 40=2x+y-eq1

x+y=28-eq2

by solving equation one and two we will get x=12

y=28-12=16 HOPE YOU UNDERSTOOD PLS MARK AS BRAINLIEST
