Answer:
8 chickens
Step-by-step explanation:
Firstly, we need to know the number of eggs produced by a single chicken in 24 hours.
Since 2 chickens produce 6 eggs in 24hours, this means 1 chicken will produce 3 eggs in 24 hours.
Now, we need 24 eggs to be produced. Since the time is the same 24hours, meaning time is constant, the number of chickens required to produce 24 eggs will be 24/3 = 8 chickens
Hence, we can say that 8 chickens will produce 24eggs in 24 hours
