Here's how the negotiations must have proceeded:
Titan: So, how much do you want?
Tiger Global: A billion dollars.
T: HAHAHAHA. (Wipes a tear). No, seriously.
TG: Um..ok, 500 million
TG: Er...how about a hundred mil?
T: Dude. Do you want to sell or not?
TG: Can I at least get my money back? I've pumped it 52 mil till date.
Titan writes out a cheque and throws a wad of cash on the table as tips. Tiger Global picks them up, gathers up his spreadsheets and PPTs and slinks out plotting how he would spin this to his LPs
Prediction: By the end of 2017, Flipkart will sell to Reliance for around a billion dollars. Snapdeal will sell to the Future Group for a third that amount.
