The Economic Order Quantity (EOQ) can be calculated using the following formula:
\[
EOQ = \sqrt{\frac{2DS}{H}}
\]
Where:
- \( D \) is the annual demand,
- \( S \) is the ordering cost per order,
- \( H \) is the annual carrying cost per unit.
Given:
- \( D = 2000 \) bulbs (annual demand),
- \( S = 300 \) Rupees per order (ordering cost),
- \( H = 30 \) Rupees per bulb (carrying cost).
Substituting the values into the EOQ formula:
\[
EOQ = \sqrt{\frac{2 \times 2000 \times 300}{30}} = \sqrt{\frac{1,200,000}{30}} = \sqrt{40,000} = 200
\]
Thus, the economic order quantity (EOQ) is 200 bulbs. The correct answer lies between 199 and 201.
