90. find the number of notes of each type.
​

Answer 1

Answer:

Step-by-step explanation:

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.
