The formula for EOQ is given by Q=2DSCPPdD=10000(365)=3650000d=10000S=180P=25000    2(3650000)(180)2250002500010000=33090.78    Q=33090.78The frequency of production runs, f, isf=Qd=3.309\text{The formula for EOQ is given by $Q = \sqrt{\frac{2DS}{C}\frac{P}{P-d}}$}\\D=10000(365)=3650000\\d=10000\\S=180\\P=25000\\\implies\sqrt{\frac{2(3650000)(180)}{2}\frac{25000}{25000-10000}}=33090.78 \\\implies Q=33090.78\\\text{The frequency of production runs, f, is}\\f=\frac{Q}{d}=3.309
