00:00Welcome everyone, so today we are going to solve a math puzzle which looks very very tricky, literally 99% of the people could not do it because see here we have 54 and then we have 405, we have 73, here we have 500, then we have 41 and this is something which we need to figure out.
00:17So now in sums like these what we should do, see because we could not do much in this case, I could do one thing very clearly, if I divide 405 by 5, I get the answer as 81, similarly here also if I divide 500 by 5, I get the answer as 100.
00:37Now this 100 is basically 10 square and this is 9 square and now if you look closely, 5 plus 4 gets you 9, 7 plus 3 gets you 10, okay so basically here what you should have gotten was what 4 plus 1 which would have gotten 5, whose square basically becomes what 125, sorry 5 square is basically just 25.
01:0725 but your answer doesn't end here, see here also all of these numbers 81, after 81, I had to multiply by 5 to get to this point, right?
01:18So here also after doing the addition and taking the square, we need to multiply this answer by 5.
01:24So answer for this question mark is supposed to be 125, I hope this is very very clear to everyone, that's it for today, I will see you in the next video.
