Interest on housing loan exemption in case of joint property

If the property is SOP throughout the year then A will be allowed 100% exemption upto limit of
Rs. 30,000/2,00,000

If it is Let out property then income will be computed as if for single owner and then it will have to be divided as 50% to each,
so in this case in effect the interest will get divided.

This is my interpretation.

Thank you!
