How many eggs?

Two hens lay 2 eggs in 2 days means 1 hen lay 1 egg in 2 days. Therefore, in 100 days, 1 hen lays $\dfrac {100}2 = 50$ eggs and 100 hens lay $100 \times 50 = \boxed{5000}$ eggs.

simple unitary method can be used to solve the problem. in 2 days 2 hens lay 2 eggs. in 1 day 2 hens lay $\frac{2}{2}$ eggs. in 100 days 2 hens lay $\frac{100*2}{2}$ eggs. in 100 days 1 hen lays $\frac{100*2}{2*2}$ eggs. in 100 days 100 hens lay $\frac{100*100*2}{2*2}$ eggs = 5000 eggs.

2 hens lay 2 eggs in 2 days, so 100 hens lay 50x2 = 100 eggs in 2 days, so 100 hens lay 50x100 = 5000 in 50x2 =100 days. Ed Gray

It takes each hen 2 days to produce 1 egg, or 1 egg/ 2 days. In a 100 day time-span, 1 hen would produce 50 eggs, which can be found by [100 days x ( 1 egg/2 days) = 50 eggs]. Since we have 100 hens and each hen produces 50 eggs over the 100 day time span, we can multiply [100 hens x (50 eggs/1 hen)] to find the total amount of eggs.

2 hens lay 2 eggs in 2 days. Accordingly 100 hens will lay 100 eggs in 2 days. And to calculate the number of eggs that 100 hens will lay in 100 days, we have to multiply 100 by 50.(100/2=50) So the answer is, 100*50=5000

• 2 hens lay 2 eggs in 2 days $\implies$ 1 hen lays 1 egg in 2 days
• 1 hen lays 50 egg in 100 days
• 100 hen lay (100 $\times$ 50) eggs in 100 days
• = 5000 eggs

• One hen - 0,5 egg per day
• 100 hens - 50 eggs per day
• 100 hens in 100 days - 50 * 100 = 5000

If 2 hens lay 2 eggs in 2 days, 1 hen lays 1 egg in 2 days which means it lays 50 eggs in 100 days. This means 100 hens will lay 100 x 50 = 5000 eggs.

• How many eggs can one hen lay in 2 days?
• How many eggs can one hen lay in 100 days?

By backtracking, 1 hen produces 0,5 eggs in 1 day. With 100 hens, that's 50 eggs a day, and with 100 days, that's $\boxed{5000}$ eggs.

2 hens in 2 days lay 2 eggs

2 hens in 100 days lay 100 eggs (Take any multiple of 2, as they lay eggs on alternate days --> 2 hens in 4 days lay 4 eggs, 2 hens in 6 days lay 6 eggs, 2 hens in 20 days lay 20 eggs & so on)

2 x 50 hens in the 100 days lay 100 x 50 eggs

That is; 100 hens in 100 days lay 5000 eggs

100 hens will lay 2 50 50 eggs in 100 days are $\boxed{5000}$ eggs in one-hundred days.
