anonymous · Answer

(5 x +20 y) = 16 days grazing rate for goats and cows right?

what is the Ans??

mrnood · Answer

you cannot answer this with the information available

You have 2 unknowns (rate of grazing for cows and goats) and only 1 equation

also - you should not expect or demand 'the answer'. The purpose of this forum is ot guide you to get the answer for yourself.

I think that that is not quite the correct equation.

There is a fixed amount of pasture available - let's call it P

if cows eat x /day and goats eat y per day then we know

16(5x + 20y) = P

Adding 5 cows gives

Z(10x+20y)=P  (where Z is number of days that pasture will provide for 5 more cows)

so 
Z(10x+20y)=16(5x + 20y)
