Explanatory Answer

Method of solving this CAT Question from Permutation and Combination: Outcome greater than the previous one

If we want the outcome in each throw to be greater than the previous one, essentially we are looking at four different outcomes in each throw and the possibility of each outcome being greater than the previous is possible only in one combination.
So, we are looking at just selecting four outcomes out of 6 possible outcomes when we normally roll a die. This is equal to 6C4= 30 ways.

The question is "In how many outcomes will each subsequent throw be greater that the previous one?"

Hence the answer is "30"

Choice A is the correct answer.
