Can bank sell my house which is on guarantee

I am in a weird situation right now, and I'd try to explain the same below. Let's call me X. There is a firm for which loan is to be taken, let's call it F. The Firm has a partner, let's call him P. F needed loan of 80 L INR, and for that X and P put their properties as guarantors and helped him get the loan. The properties that were put as guarantee are as below: - X - 46L - P - 56 L So, total value of property is 100L on which bank has given Credit limit of 80L. Now, F is bankrupt, and is not able to pay the loan or interest of the loan, which lead to the account being declared as NPA. Understanding the gravity of the situation, I am ready to pay 40L, which is more than the share of loan that was given on my property to bank, but bank manager told me that unless 80L would be paid, my house cannot be saved. By this, it seems that if I have property worth 90L on guarantee and another person has 10L property on guarantee, then due to other person not paying his dues, my property would be sold as well. I don't think that should be allowed, but am not a legal expert. The bank in consideration is Central bank of India. And I am planning to go ahead and hire a lawyer and file a case to save my house. Any help in these regards would be highly appreciated.
