If anyone has confusion try this! Find ratios of each row(by dividing solution to key column value) and select least positive value from ratios and that particular row become key row Then proceed further

thank you mam for such an nice explanation . all the diubts of mine are solve .

[@aasthayadav5784]

Hello Ma'am, your videos are great and really helpful. I have a doubt regarding, why are we not using the "Ratio column" in the simplex table. In our previous problems on normal maximization and minimization, the key row was selected by choosing the least positive value from it (Please correct me if it is least non negative i.e. if zero counts). Here we went for directly the largest value from the solution column, I'm a little lost here.

[@drevathy1006]

Same doubt 🥺

[@avinashandepu21]

Same douht, may be it's a mistake ,to find ratio we have devide the solution with key column eliments,in this problem 1÷(-1)=-1, that's why mam select highest positive but it's a only positive value

[@tushargogiya4017]

Same doubt at the end of my college teacher do same thing with same example without telling anything...💀😂

[@manassehpauladaikalam9029]

when the solution value is divided with the corresponding key column value we need to consider least positive value of ratio column. but in order to save time, this is considered coz dividing will yield a lower solution.

[@abhishekkuntal2427]

Hello mam, i have just one doubt In this video you have said that for finding the key row we need to find the most positive value whereas in the simplex method we use the ratio and then find the smallest ratio to decide the key row. Though there is no conflict in this particular problem between the two methods, in some problems the conflict may occur, so could you please tell me which method should be followed?

[@chandreshgauns29]

I have same doubt

[@rajsakhrekar1339]

Highest ratio value is considered in minimization problem, whereas lowest ratio value is considered in maximization problem

[@CodesVision]

Yes mam!...me too have same doubt.....i solved questions before watching your video ..and for optimal solution all Zj-Cj>=0 but according to condition you applied cj-Zj for optimity ,,we should have Cj-Zj

[@ijabulsheikh5734]

I have same doubt

[@bizen5872]

U do very easy problems its easy to understand steps but if tough problems come cant do this type like 3 constraints Please do tough problems and explain in easy way to understand

[@kalashnikov203]

I have a doubt. Why aren't we using minimum positive value of the ratio column (solution column divided by the key row column) like in other simplex problems? Here ma'am used maximum positive value of the solution column instead.

thankuu so much 😇😇

Y you are taking most positive element in cj-zj . in Simplex we take least positive element only la Pls clarify my doubt mam

[@johnjoe9397]

Ma'am in the simplex method video you said we should select the largest cj-zj value but here u have selected the least value.similarly while key row selection u did not take the ratio of solution by key column..which is the correct procedure?

[@suvarnasuresh8755]

In simplex method it is a maximization problem. But here minimization problem is discussed. So we take least cj-zj value

why in simplex method that being shown by this madam that the leaving variable is exist in collumn but in two phase method, the leaving variable is not exist ?
