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

\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.

Another possible way of looking on the problem: The answer is 0, because if you have a chicken and a half, the chickens are dead 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! Anyway, back to the problem, I go with 6.
