Answer 2

Answer:

20 coconuts

Explanation:

First 10 checkpoints

1@ x 3 boxes x 10 checkpoints (i.e. 3x10) = 30

leaving two boxes (60 mangoes)

next 10 checkpoints

1@ x 2 boxes x 10 checkpoints (i.e. 2x10) = 20

leaving one box of 10 and one box of 30 (40 mangoes)

final 10 checkpoints

1 @ x 2 boxes x 10 (i.e. 2x10) = 20  

Leaving 20 mangoes.
