Capital gain

I think fair value as on 1981 is required for this,

if fair value on 1981 is also 4635,then RS,23170 will be the correct answer,(assuming expenses for sale=0)

       SALE PRICE                   =15,00,000

LESS:COST OF AQUISITION =4645*785/100

                                                =36463

     COST OF IMPROVEMENT  =200000*785/109

                                                =1440367

LONG TERMCAPITAL GAIN    =1500000-1440367- 36463 

                                                =23170                                       

IF EXPENSES ANY FOR THE PURPOSE OF SALE CAN BE DEDUCTED FROM IT.
