So there was a corporate action like stock split or bonus or something like that. Assuming there was stock split, share price will drop to 475 (instead of 1 share at 950, u have 2 shares at 475). So all strike prices will also reduce on that day. New strike price will be 450. So instead of 250 quantity short at 20 of 900 puts , you will have 500 short puts at Rs 10 of 450 puts. Since stock is at 450, you make the entire Rs 5000 as profits ( 500 x 10)
