A basket contains apples and oranges in a 4:3 ratio. If 6 more apples are added, the ratio becomes 2:1. How many total fruits were in the basket originally?
21
Let apples be 4x and oranges be 3x. (4x + 6) / 3x = 2/1. Cross multiply: 4x + 6 = 6x => 2x = 6 => x = 3. Original total = 4(3) + 3(3) = 12 + 9 = 21.
