Question

1. A certain number of 10 notes and a certain number of 50 notes are kept in a purse so
that there are 60 notes in the purse and their total value is 1400. Find the number of
each type of note.

Answer 1

Answer:

NO. OF RS. 50 NOTES = 20 NOTES

NO. OF RS. 50 NOTES = 20 NOTESNO. OF RS. 10 NOTES = 40 NOTES

Step-by-step explanation:

TOTAL NO. OF NOTES = 60

LET THE NO. OF RS. 50 NOTES BE x AND THE NO. OF RS. 10 NOTES BE 60 - x

(50 × x) + (10 × (60 - x)) = 1400

50x + 600 - 10x = 1400

40x = 1400 - 600

40x = 800

x = 800/40

x = 20

NO. OF RS. 50 NOTES = x = 20 NOTES

NO. OF RS. 10 NOTES = 60 - x = 60 - 20 = 40 NOTES

Answer 2

Answer:

Step-by-step explanation:

Let the number of $10 notes = x

The number of $50 notes =20 - x

Value of $10 notes = x× $10=$10x

Value of $50 notes =(60-x)×$50=$(3000-50x)

Total value of all notes =$140

20x+(3000-50x)=140

10x+3000-50x=140

-40x=1400-300

-40x=-1600

x=-1600÷-40=40

The number of $10 notes =40

the number of $50 notes=60-x=60-40=
