Question

If 4 goats or 6 sheep can graze a field in 40 days, how many days will 4 goats and 14 sheep take to graze the same field?​

Answer 1

Answer:

The given information is NOT insufficient, as the other tutor said....

4 goats can graze the field in 40 days; so it would take 1 goat 4*40 = 160 days.

So 1 goat grazes 1/160 of the field in 1 day.

It takes 6 sheep to graze the field in 40 days; so it would take 1 sheep 40*6 = 240 days.

So 1 sheep grazes 1/240 of the field in 1 day.

If there are 4 goats and 14 sheep, the fraction of the field grazed in 1 day is

4%2A%281%2F160%29+%2B+14%2A%281%2F240%29+=+12%2F480+%2B+28%2F480+=+40%2F480+=+1%2F12
