Buyback query average price

I bought 50 shares at 195 on day 1 and 50 shares at 190 on day 2. I surrender in buyback 50 shares @215 as it’s acceptance ratio is 50% what will be my average price of remaining holding shown ? 190 or 192.5… there is no FIFO in buyback debit ??

Tendering for a buyback is essentially a sale. FIFO will be applicable to buy average calculation.
