Explanation:

again B1 : B2 : B3 = 5y : 4y : 3y
Since there is increase in no.of oranges in first two baskets only, it means the no. of oranges remains constant in the third basket
Therefore, 5x = 3y
Hence 3x : 4x : 5x => 9y/5:12y/5:15y/5 = 9y:12y:15y
and 5y : 4y : 3y => 25x : 20x : 15x
Therfore, increment in first basket = 16
Increment in second basket = 8
Thus, required ratio = 16/8 = 2:1
