Let the price of variety 2 be x. Then, the price of variety 1 is 2x. Selling price = 125% × cost price Cost price of mixture = 28 × (100/125) = Rs. 28 × (4/5) Cost price of variety 1 + cost price of variety 2 = 2x × (2/5) + x × (3/5) => 2x × (2/5) + x × (3/5) = 28 × (4/5) => 7x/5 = 28 × 4/5 => x = Rs.16
