While the lot size will be adjusted to 750 (Current lot size: 150 * Adjustment Factor: 5).

Strike Price: The adjusted strike price will be arrived at by dividing the old strike price by the adjustment factor.

Lot Size: The adjusted lot size will be arrived at by multiplying the old market lot by the adjustment factor. The revised lot size would be 750.
