Answer 2

Answer:

1 ₹ coins = 80

2 ₹ coins = 60

5 ₹ coins = 20

Step-by-step explanation:

Let the no. of Rs. 5 coins be x

Then,

No. of Rs. 2 coins will be  3x

So,

Rs. 1 coin will be =  160-3x-x = 160-4x

The amount with me = 120 ₹

From Rs. 2 coins = 3x = 3x2 = 6x

from Rs. 5 coins = x = 5x

from Rs. 1 coin = (160-4x)x1 = 160-4x

Total money Rs.300

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

7x + 160 = 300

7x = 140

x = 20

No. of Rs. 2 Coins = 3x20 = 60

No. of Rs. 5 coins = x = 20

No. of Rs. 1 coin = 160-4x20 = 80
