If ratio of cost price to selling price is 5 :7 ,find the profit percentage, tell me​

let the cost price = 5x

let the selling price = 7x

profit = selling price - cost price

= 7x - 5x

= 2x

profit percentage = 2x/5x × 100

= 2×20

= 40 percent

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
