A few notes: At 18:08, when imagining two horses being below the average and one above the average, I should say that in that scenario I need the other three horses to be exactly 17K. That is, the inference of 'their average is 16.5K' applies when I know exactly two horses are below the average, and exactly one horse is above the average at 18K. Around the 1:17:00 mark, talking about range vs. # of numbers, should have mentioned the formulas for # of numbers: Range/'counter' + 1, where 'counter' is whatever your spaces are. So for consecutive integers, 'counter' would be '1.' For multiples of 3, counter would be 3.
Sir question in which median of set E is asked 1) tells about average of x and y is average of set "S" Does set S and E mean same or first sentance is not mean anything and answer will be (2) Please elaborate. Thanks
I think there is some mistake in question discussed at 52nd minute. Answer is option A Logic - 1 to 62% will own 1 yatch and 38% (62 to 100%) will own 2 However, I can have the case where everyone from 1 to 38% own 2 yatch and then other own 3 so the median will be 2

Nice

Oh that's a dumb typo. I meant to make them the same set name.
I think there is some mistake in question discussed at 52nd minute.
Answer is option A
Logic - 1 to 62% will own 1 yatch and 38% (62 to 100%) will own 2
However, I can have the case where everyone from 1 to 38% own 2 yatch and then other own 3 so the median will be 2
use a pen mouse or a mouse pad instead of a classical mouse...
