A landlord sold development rights to a builder against which Builder has agreed to pay him consideration  40% in cheque and rest 60% as a Flat will be constructed by him for the landlord.

Cheque amount is already received in parts i.e in F.Y 15-16 and F.Y 17-18. 

So how capital gain should be calculated and which year it should be offer for taxation?
