Sorry, I'm a bit stuck at the train of thought starting at 27:07. Why are we looking only for the 3's? As you said, we're looking for the 2's AND 3's, but then we end up ignoring the 2's anyway? Nevermind: I got it now :D

[@shwetaj4919]

what is the reason?

at 18:17 where did she get the 2 in the units digit...isnt it 4 times 6 times 3

[@poojashah3345]

Yes, 4 times 6 times 3 is 72 and the units digit of 72 is 2

no perfect squares end by 2,3,7,8 add + 1 to all ans choices see if its a perfect sq or not. the one which isnt a perfect sq --> is the ans we are after
