 अगर वो नाभ भेट सका तो वो जों वो हैं नूसपेप पर पबलिशर वो वो उसको 30 संच पर कोपी पेबैक करेंगे, तो सालवेज वेलु उसकी 30 संच की बन जाएगी, बड़ में कि सेवंटी का वो ख्रीटर अर, बड़ी विल गेड़ बैक तो वो वो वो वो वो वो वो व यह समें था अगर भीं रव िद हो, पर कोपीग spaces whale in your due for the tort and as01 भी नाभ बेटेः नाधनलूड, अगर को मेखे निए वुना where is an idea cows . planned cost of under stop. price is 55% or $0.55 and cost of overstock is 40% and $0.40 is its cost of overstock and if we calculate the service level on this basis to 55 divided by 55 plus 40 gives us 0.579 now we have to see what is the value of 0.579 against z because we have to see the standard normal distribution table so we have to see what is the value of z because z multiplied by standard deviation if we look at the table, the value of z is 0.2 so this is the value of z against this probability 0.579 so the value of z is 0.2 we have to use this and that is your order size that is the average demand plus z multiplied by the standard deviation so if we do this, our order size is 123 papers for this situation, this condition and if we see the stock out risk then 0.579 is in stock so 1 minus 0.579 which is 42.1% this can be out of stock this table of the normal distribution we have seen that 0.579 is the value of z so we have to see the values of 0.579 these are probabilities and the leftmost column that is the value of z and these values are added in this column so this probability falls so 0.5792 comes somewhere here which is the value of 0.5793 so it is the closest and if we look at this on the left side then it is 0.2 and if we look at the top column then it is basically 0.0 so 0.2 plus 0.0 is 0.2 so the value we used for z is the value of 0.2
