Answer 1

hy

friend

here is your solution··········

lets assume you have ∞

≡ x notes of rupees 5

≡y notes of rupees 10

x+y = 90

and 5x + 10y = 500

putting

x= 10 - y in second equation you have

first step

➡5 [90 - y] + 10y = 500

➡450 - 5y + 10y = 500

➡5y = 500 - 450

➡ y = 50 / 5 = 10

second step

x = 90-10

= 80

so answer is 80 notes of rupees 5 and 10 notes of 10
