Question

a purse contains rupee 5000in notes of denominations of rupees 100 and 500 .if the total number of notes is 30 find the number of notes in each denominations

Answer 1

Answer:

Step-by-step explanation:

Let number of rs.500 coins=x

Then number of rs.100 coins =30-x

Value of rs.500 coins= rs.500x

Value of rs.100 coins=rs.100(30-x)

=3000-100x

Apq.

500x+3000-100x=5000

400x=5000-3000

x=2000/400=5

No. of 500 coins=5

No. of 100 coins=30-x=30-5= 25

Answer 2

Hey....!!!

Let the no. of Rs 100 notes be x
Therefore, no. of Rs 500 notes = 30 - x
Total amount = 100x + 500(30-x)
. = 100x + 15000 - 500x
. = 15000 - 400x
According to the question,
15000 - 400x = 5000
=> - 400x = 5000 - 15000
=> - 400x = - 10000
=> x = - 10000/-400
=> x = 25
So,
No. of Rs 100 notes = 25
No. of Rs 500 notes = 30 - 25 = 5

Hope it helps...!!!
