Answer / praveen
let c be the quantity eaten by each cow per one day...
let g be the grass quantity...
then from the first statemet 40*(c)*40=g
then c = g/(1600)
now consider 20 cows...each day they will take 20*(c)grass
i.e., 20*(g/1600)=g/80...
=> each day they complete g/80th part.
therefore they can complete in 80 days...
now come to the second statement...
for 30 cows...30(g/1600)...t.e., they can complete in
160/3 days ...so second statement is wrong...

Answer / surya teja challapalli
No of days is inversely proportional to no of cows.
Here no of cows is decresing by 10,no of days increasing by
20.
40->40
30->60
20->80
No of days taken by 20 cows to eat the grass=80.
