THE ACTUAL QUESTION IS THIS....

..........................................................

3 cows graze the field in 3 days and 2 cows graze the field in 6 days then how many days does it take 1 cow to graze the complete field?

mathematical answer

-------------------------------------------

let

one cow graze th field in n days

initially length of the grass = g.

grazing rate for the cow= r;

growing rate of the grass =R;

now

g+ no.of days* grazing rate=no. of the cows *no. of days *grazing rate.

g+3*R=3*3*r ---------->(1)

g+6*R=2*6*r ---------->(2)

g+n*R=1*n*r ----------->(3)

on solving the equation (1) and (2)

r =R

i.e. grazing rate = Growing rate

hence

we can say that one cow can not finish the grass from the field

manually

put r =R in equation (4).

g+n*r=n*r (Invalid equation )

without using mathematic we can also solve it logically

-----------------------------------------------------------------------------------

as we know that grass is continuously growing, if cow is grazing at one place, grass id growing at other places, hence it can not be finished

It is known that 40 cows can graze on a pasture for 40 days before the grass is exhausted but 30 cows can graze there as long as 60 days How many would the pasture last if 20 Cows were to graze on it?

If 40 cows can graze the pasture for 40 days and 30 cows can graze it for 60 days, this means each cow eats 1/40 of the grass per day in the first scenario and 1/60 of the grass per day in the second scenario. To find out how long 20 cows would take to graze the pasture, we calculate that they would consume 1/40 * 20 = 0.5 of the grass per day. Therefore, the pasture would last for 80 days if 20 cows were to graze on it.

Assuming each cow consumes the same amount per day. The farmer has enough for: 30 cows*28 days = 840 cow days or 840 cows for 1 day Therefore he can feed 840 cow*days/35days = 24 cows for 35 days. 30 cows - 24 cows = 6 cows The farmer must get rid of 6 cows.

What is a cows life like?

A cows life is often rather boring. Although they do like grass and being milked, they most likely must get bored of this repetitive life style, especially as they don't have Christmas and birthday and things. Anthropomorphizing like the above person does doesn't help answer the question. Cows are creatures of habit, and are happy with how things go day to day. They eat, sleep, have sex when they're needing it, and get milked...at least for the dairy cows. For the beef cows, the same applies above except they got a calf to look after and open skies to graze under all day. They couldn't be happier.
