Detailed Solution

It is given that a field can be grazed by 44 cows in 9 days.
We know that the two variables are said to be inversely proportional if and only if they are directly proportional to one another's reciprocal. If x and y are two variables in inverse variations, then
    x 1 y x=k 1 y x= k y ,        where k is proportianality constant xy=k                                                   ....(1) Let the number of cows that graze a field in 12 days is x. From the given data, we can draw a table as,
Question ImageSince, on increasing the number of cows, there will be a decrease in the number of days, therefore this is a case of inverse proportion. Thus,
44×9=x×12 x= 44×9 12 x=33
Therefore, 33 cows will graze the same field in 12 days.
Hence, option (4) is correct.
