Question

if 14 cows can graze a field in 12 days . 21 cows will graze it in how many days​

Answer 1

Step-by-step explanation:

If more number of cows, less number of days required to graze the field. Therefore it's inversely proportional.

Let us consider the required number of days to be x, then 

6×28=14×x

x=(6×28)/14=12

∴12 days are required
