Question

a sum of rupees 500 is in the form of denominations of rupees 5 and 10 is the total number of nodes is 90 find the number of notes of each denomination

Answer 1

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.
