Question 252170
This question is about proportions. Let B = banana, C = coconut, F = fish and H = hammock.

50B = 20C ; 30C = 12F. The least common multiple of 20 and 30 is 60. So,

150B = 60C ; 60C = 24F. More succinctly, 150B = 24F.

Now, 24F * 4 1/6 = 100F, so

150(4 1/6)B = 625 B.

So, it will take 625 bananas, or (B)
