Answer 1

1x : 1 6667y

Step-by-step explanation:

Let :

unit of Rs. 60 per kg = x

Unit of Rs. 72 per kg = y

60x + 72y = 64.5(x + y)

60x + 72y = 64.5x + 64.5y

60x - 64.5x = 64.5y - 72y

-4.5x = - 7.5y

Divide both sides by - 1.5

3x = 5y

x = 5/3y

It could be mixed in the ratio ;

1x : 1.6667y
