Doubt:free samples received

17 packets at average cost.

salman is right. let me explain wid an example:

if u purchased 12 pac. + 5 free Pac. for Rs. 204 (ie 12Pac x Rs. 17/-per Pac + 5 Pac x Rs. 0/- per Pac)

now the Avg cost per Pac is Rs. 12/- and not Rs. 17/-

Avg Cost Per Pac = Total Expenditure / No. of Pac received

how comes: Rs. 204 / 17 Pac. = Rs. 12/- per Pc.

 So it should be taken at average cost.........ok got it....

 thank you very much to Naveen and Salman
