How will ito treat this situation ?

Since u say such plot is situated in rural area (please read the definition of rural area), then CG is not taxable in the hands of the seller, as such asset is not regarded as capital asset. Hence there may not be any tax liability even to the buyer for inadequate consideration.

Respected poorniam ji :: I think , The area which is situated very far from city or urban area or outside muncipal corporation boundry , where Panchayati raj works called Rural Area . The plot is also situated very far from city , outside muncipal corporation boundary and also where there is a plot , panchayati raj works . Panch and sarpanch are there .

Now , is that plot in rural area ? if yes then , can i buy that plot for rupees 1 lakh which is less than govt guideline rate ?

Yeah, u can buy it if u r sure that the plot is in rural area in which case there will not be any taxability on account of inadequate consideration in ur hands. Utility to check whether urban area: https://www.incometaxindia.gov.in/Pages/utilities/Agriculture-Land-in-Urban-area2014.aspx.
