Is CAT Registeration number and User ID Same.?

Hi Yes CAT registration number and user ID is same for CAT.

The registration number is not mentioned anywhere. I checked. Only User ID.

Can I discuss my preparations with one of the mentors? Can I call someone from cracku to discuss my study?

Sadly, this is one area that Craku needs to improve upon, there is no interaction between students and faculty, no ask me anything sessions while the other providers do this!

I think there should be seprate group for paid members either on telegram or facebook

If 16 oranges are distributed among 4childrens such that each gets atleast 3 oranges ,the number of ways of distribution them is .

I assume the oranges are identical. We have to give 3 to each of them that consumes 12 of them. The remaining 4 can be distributed using the formula of distributing n identical objects into r different group where each group cab have 0 or more(n+r-1Cr-1). The answer will be 35(n = 4 and r = 4).

Assuming that the oranges are identical, remove 12 oranges (3*4) as each of the four people should get atleast 3 oranges each. So, we have to distribute 4 oranges amongst 4 people. a+b+c+d = 4. Number of solutions is 7C3 = 35
