Apple Banana and Coconut Puzzle

1 apple + 1 apple + 1 apple = 30
3 apple = 30
so 1 apple = 10.

1 apple + 3 banana + 3 banana = 18.
10 + 6 banana = 18
6 banana = 8 
3 banana = 4.( lets dont calculate 1 banana value because we dont need it )

3 banana – 2 coconut = 2
4 – 2 coconut = 2
2 coconut = 2
coconut = 1

1 apple + 1 coconut + 3 banana
10 + 1 + 4 = 15

So Final Answer is 15.
