humber of notes of each type. ?​

Answer 1

Answer:

Rs.5=80 notes

Rs.10=10 notes

Step-by-step explanation:

Lets assume you have x notes of rs 5 and y notes of rs 10. So you have

x+y =90

And 5x+10y=500.

Puting x=10-y in 2nd equation you have

5(90-y)+10y=500.

450–5y+10y=500

5y=500–450

y=50/5=10.

Hence x=90–10=80.

So ans is 80 notes of rs 5 and 10 notes of 10.

Answer 2

Answer:

• No. of Rs. 5 notes = 80
• No. of Rs. 10 notes = 10

Step-by-step explanation:

Given

• A sum of Rs. 500 in the form of denomination of Rs 5 and Rs. 10.
• Total number of notes = 90

To Find:

• Number of notes of each type.

Now, let Number of Rs. 5 notes = x

And, Number of Rs. 10 notes = 90 - x

Now, Total amount = Rs. 500

Now, according to question,

=> 5x + 10(90 - x) = 500

=> 5x + 900 - 10x = 500

=> - 5x = - 400

=> x = 400/5

=> x = 80

Hence,

• No. of Rs. 5 notes = 80
• No. of Rs. 5 notes = 80No. of Rs. 10 notes = 90 - 80 = 10
