Sorry if this was already mentioned but in 30:14 there is a small mistake: it's not "smaller than 4000 i.e. up to 3999" but "not greater than 4000 i.e. up to 4000". So the correct answer is 3x5x5x5 + 1 (which is "4000"). So the answer 376.

Dear teacher, I am from Iran and found your videos really helpful. Thank you so much.

[MP-rurx]

You are the best explainer I have found on youtube!

ay 29:39 for the CAT 2008 que, it says not greater than 4000, so it can be equal to 4000, right?

At 4:28 the answer would be 4)625 if the question was opposite ? Like if the children come to get the chocolates instead of chocolates been distributed to them ?

answer at 31:44 should be 376 because 4000 will also be included as a 4 digit number which is not greater than 4000.

I was struggling in this bcs I forgot the concept. U just made easy. Thanks.

[revanthvardhan]

at 30:20 greater then 4000 means doesn't it mean that 4000 also includes in the range??

an excellent video which i wish would have been there when i was appearing my 10th boards. Express my heartfelt gratitude pushpinder and perfect scores for having made the concepts of permutation and combination so easy.

I think the problem at 35:50 is solved wrong. A "Does not want to sit on even no of chairs" -> according to your solution A wants to sit on even number of chairs.
