Answer 1

Answer:

20 20rupees notes 500rupees. 30 10rupees notes 300rupees 500+300=800. hope it helps you

Answer 2

let x be the 10 rupees notes

let y be the 20 rupees notes

10x + 20y = 800 ..........1

x + y = 50

10 (x + y = 50)

10x + 10y = 500 .........2

Subtract equation 2 from 1

10x + 20y = 800

-10x - 10y = - 500

10y = 300

y = 30

x = 20
