Spending 15 seconds on this question, I am hesitating between 8 and 9. My gut tells me 8 and my head tells me 9. I will go with 9, E

This is a classical work problem. 1,5 chickens lay 1,5 eggs in 1,5 minutes that means 3 chickens lay 3 eggs in 1,5 minutes and that means 3 chickens lay 6 eggs in 3 minutes

gmate2010 · Answer

\frac{3}{2}  chickens =  \frac{3}{2} eggs / \frac{3}{2}minutes 
 => 2* \frac{3}{2} chickens = 2* \frac{3}{2} eggs / \frac{3}{2}minutes  -- Multiply by 2 both sides

=> 3 chickens = 2*3 eggs/2*\frac{3}{2} minutes  -- Multiply by 2 in the right hand side( both numerator and denominator)

=> 3 chickens = \frac{6 eggs}{3 minutes}

Hence, answer is 6.

Maybe the single alive chicken increases rate of production looking at the half dead chicken. Either make some more eggs or be someone's lunch! :-D

Anyway, back to the problem, I go with 6.
