[@bittudangi6742]

After attending your lecture... Aptitude became my favorite subject.... Thanks you sir..

[@debdiproy8916]

Are sir ji,😱khatarnaak parhate ho aap....crystal clear concept ho gya, sir.

[@SKS-ec2ki]

sir mujhe pehle p and c bilkul nhi ata tha lekin abhi sir pure questions baan jaa raha hai p and c ke ,thank u so much sir 💯

[@AJitKumar-vg6no]

Sir ! Answer to Q-15 should be 575 as 576 includes 5300 which is not a valid combination

[@SKS-ec2ki]

YAA BRRO👍

[@Motivational.daily134_5]

After watching Avinash sir lecture permutations and combinations seems to be easy ❣️❣️

[@criminalcoder6307]

Views not specify your teaching uniqueness sir. Best aptitude class for pnc ever.

[@AhsanAli-ns5gn]

Time - 1:42:30, in question no. 15, the given condition is "greater than 5300", not greater than or equal to 5300, so the first part answer should be 3*4*5*6, instead of 3*4*6*6, right sir?

[@kruz2919]

No, the total no.of ways would be 575. Why? See, if you don't consider 0 in the tenth or zeroth place, we are possibly neglecting a valid way like, 5302 if we neglect tenth place 0 or 5320 if we neglect zeroth place 0. But, if we look carefully, there is only 1 possible way 5300 would occur considering all repetitions and 0s in the tenth and zeroth place. So we have 576 - 1 = 575 ways. What you are suggesting would happen if we didn't consider the repetitions, got it? I also got confused at first ;)

[@ritukumari-kz9jw]

[@danishkhan7001]

We can repeat the numbers that's y 7 can be included at 1st place so total numbers at 1st place will be 5.
