Question

Needing help, the secretary of the united states department of agriculture asked your teacher, "if a chicken-and-a-half can lay an egg-and-a-half in a day-and-a-half, how many days will it take three chickens to lay thirtytwo eggs?"

Answer 1

we are given that

3 chickens to lay 32 eggs

now, we can find number of eggs per chicken

number of eggs per chicken= (total eggs)/(total chicken)

so, we get

number of eggs per chicken is

$=\frac{32}{3}$

now, we can set up following

1.5 chicken : 1.5 eggs : 1.5 days  

3 chickens : 3 eggs : 1.5 days  

1 chicken : 1 egg : 1.5 days

Since, changing number of chicken won't affect time

time to lay eggs will always remain same

so,

for 1 chicken to lay $=\frac{32}{3}$ eggs

it takes

$=\frac{32}{3}*1.5 days$

$=16 days$..............Answer
