Answer 1

Answer:

• Let the number of Rs 5 notes be x

• Total number of notes = 90

• Hence the number of Rs 10 notes be (90 − x)

• Total sum of money = Rs 500

∴ 5x + 10 (90 − x) = 500

5x + 900 − 10x = 500

− 5x = 500 − 900

-5x = −400

∴ x = 80

Hence there are 80 notes of Rs 5

Number of Rs 10 notes = 90 - 80 = 10

Hence there are 10 notes of Rs 10.

Answer 2

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.
