Feel free to solve it

Since $5$ cats can catch $5$ rats in $1$ minute, that means $n$ number of cats can catch $n$ number of rats in $1$ minute as all the cats are trying to catch their corresponding rats at the same time. So, if we take $n=30$ , we can say that $30$ cats can catch $30$ rats in $1$ minute. So, the answer is $=\boxed{1 \text{ min }}$

5 / 5 = 1 ,,, 30 / 30 = 1.. :)

ratio of rats to cats is equal in both cases, so the answer is the same

reading the question we can guess

30 cats can catch 30 rats in 1 min.

1cat & 1 rat = minute = 30cats & 30 rats = 1minute

this is simple .one cat catches one rat in one minute .so thirty cats catches thirty rats in one minute.

well that's common sense...isn't it?

Each cat is catching one rat in a minute,so 30 cats will catch ,30 rats in a minute. Ans

5cats:5rats in one minute 30cats:30rats in m? from the given above, we can conclude that the ratio of catching a rat in one minute for every cat is one.. therefore still the answer is one

if 5 cats can catch 5 rats in one minute then as long as there are the same number of cats as rats then it can happen in one minute vote up

Since cats can catch rats in 1 minute, so 30 cats can catch 30 rats in 1 min.

simply if 5 cats can catch 5 rats in a mints then 30 cats can do this in 30 mints
