Answer 1

Answer:

Rs. 5 coins= 20, Rs. 2 coins= 60, Rs. 1 coins= 80

Step-by-step explanation:

Let be the number of 5 rupees cions = Rs.x

let the number of 2rupees cions = 3x

let the number of 1 rupees coins = 160 - 4x

then total amount of 5 rupees coins = 5x

then the amount of 2 rupees coins = 6x

5x + 6x + 160 - 4x = 300

7x = 300 - 160

7x = 140

x = 20

There fore,

the cost of 5 rupees coins =20

the cost of 2 rupees coins =60

the cost of 1 rupees coins=80
