Awesome explain sir, today i learn something new , Thank you so much sir 🙏

[@riya-xp9sc]

Nice and simple approach sir for every ques

[@dollysingh7745]

You teach every concept properly

[@DrHarishGarg]

Thanks dear..... Keep watching and sharing

[@Rahi310]

Every concept u connect is very smartly ..nyc explanation

[@DrHarishGarg]

Thanks a lot... Keep watching and sharing with others too

[@roy.anwesha3107]

very helpful video. thank you so much.

[@anikumari4423]

Thank you so much sir this video is very helpful

[@shiprarani2808]

Sir, In Q32 we have given with bounded feasible solution i.e. -5

[@DrHarishGarg]

Will check and inform u soon

[@AmitaVarshney]

Q55 dual 2Y1+Y2+2Y3 hai

[@mohitsingh9701]

Excellent 👍☺️

[@ronneysaini7763]

Superb Solution Sir ji😍

[@DrHarishGarg]

Thanks.

[@avaypati]

sir in Q32 you mentioned that the given lpp is bounded so how cann the feasible region be unbounded. please explain sir

[@donexbaghouserishikesh6199]

Right pls reply sir

[@Gayanibaba_in_math]

Because one option must be true...

[@barnanandi915]

Nice explanation of the complementary slackness theorem.

[@artidevi8628]

Thank you so much sir 😊

Last question me dual ki equations me equality kyo li apne

[@DrHarishGarg]

Check the primal variable value. As it is zero thus corresponding constraint is equality. Example, if x1=0 then 1st constraint of dual satisfy equality, same for x2 and others.

[@shivanigoel5724]

@@DrHarishGarg ok thnx

[@tanutyagi3848]

But in last question you said s3=0 but we find s3 is non zero then why you can say y3=0

[@AnjaliSharma-go6ps]

you said that optimal solution of primal and dual are same then why the optimal and primal solution would be different in question number 55 please explain

[@DrHarishGarg]

In both sides.. Optimal value Z is 46/3 which is same....

[@satyamtiwari7217]

@@DrHarishGarg p+q+r should be equal to X1+X2+X3 as you said the optimal value of l.p.p and dual will be equal

[@mridulsaini2894]

​@@satyamtiwari7217 Try to understand, value after replacing x1,x2,x3 in Objective function of primal is equal to the value after replacing y1,y2,y3 in Dual; i.e Value of objective function is same not of variables.
