How to recharge with exact amount

[sumeet12345]

HI, i have recently taken 3g connection...there is a pamphlet of bsnl which says Rs. 249+taxes for recharge of 0.5 gb...now the confusion is that the shopkeeper says its Rs.274 for 0.5gb....another shopkeeper says its Rs.275....if i dont recharge with the exact amount that is required then that money will go as talktime or if i do internet then i will be charged Re 0.5 for 1mb....my question is whats the exact amount not only for 0.5gb but also for 5gb plan and unlimited plan.....if someone has taken up some plan then can he tell me the specific amount for that plan.

I though these data recharges were usually preceded by special code like STV, FTV or something like that to avoid messups.
