How come Raju Rangeela guessed that Karan had given 10 lac rupees? 'Cos Karan was surprised/shocked when Raju/Dev mentioned the amount to him and gave him the bundle ( Although, later Karan becomes suspicious since he finds that Raju/Dev hasn't broken the safe) Dev is just marvellously trying to potray RR (Kudos to Apurva!!!) He is giving an amazing performance in both the roles. So is Surveen!
