How tax will be computed for buy/sell property

Hi,

Have one property purchased @ 84.15L in 2016. Now I want to sale this property and buy different property. The selling price is 91L and buying price for other property is 92.5L . Also, will be buying new property before selling.  Queries:
a) What will be the capital gain tax.
b) Can it be adjusted as i am selling and property and buying the another one. But buying will happen before selling property for around 2 months.
c) What will be TDS deducted for buying the property @ 92.5L
 

Regards,

Rajiv
