Answer 1

Answer:

number of 10 rupee coins is 5

let the number of 10 rupee coins be x

then number of 100 rupee coins will be 3x

number of 500 rupee coins will be 3x+5

value of 10 rupee coins will be 10x

value of 100 rupee coins will be 300x

value of 500 rupee coins will be 1500x+2500

10x+300x+1500x+2500=11550

1810x=11550-2500

1810x=9050

x=9050/1810=5
