Property registration by general power of attorney

Propert purchased by A in 1992 for Rs.92000 by GPA, in 2013 A registers property in his name stating purchased for Rs 34 lacks(considration paid in cash, but actually no considration was paid as it was getting registered in his own name) 

so the property should be shown at what price in the year 2012-13 and 2013-14.

Whether any tax is attracted in such case?
