If 40 of Bonny’s parrots feed on wheat, how many of the wheat feeding parrots are green?

I think statement is confusing : among the pink parrots, those that feed on soy beans are twice as many as those that feed on wheat. Second those is ambiguous whether it refers to all parrots or pink parrots.

Solved using single variable "x" Refer diagram for details. We require to find the value of the green shaded blockTotal Pink = x Total Green = 3x Total Parrots = x + 3x = 4x Total Parrots = Total Green + Total Pink = Total Wheat + Total Soy = 4xParrots on wheat = 40 So, Parrots on Soy = 4x  40 1/2 of Parrots on Soy are green So, Green Parrots = 2x20; so pink would be same = 2x  20 Among the pink parrots, those that feed on soy beans are twice as many as those that feed on wheat 2(20x) = 2x20 x = 15 (20+x) = Green Parrots on Wheat = 20+15 = 35 Answer = C
