OBJECTIVE: In the empty grid, which represents garden, you should set as much as you can of tromino shaped (both kind of trominos) of apples and bananas orchards. Orchards of different kinds can touch each other by side, but orchards of the same kind can touch each other only diagonally. For "cornered" tromino (apples) please type letters A, and for straight one (bananas) please type letters B. Numbers of cornered and straight trominos don't have to be equal. At the end, due the calculation reasons, please type X in the yellow field.
CALCULATION: Numbers covered by apples (A) are multiplied by 2 and numbers covered by bananas (B) are multiplied by 3 and all of these numbers are summed. Numbers on unused fields (weeds) are multiplied by 5 and subtracted from the result. Maximize your result.
