Assuming you can recharge as much as possible and the recharge amount can be very very small ie., a lot lower then a paise, then a recharge amount of 200 is possible after infinite recharges or in other words recharge of an amount a little less than 200 is possible after a large number of recharges.
If 1 paise is the lower limit for recharge, then only after 14 recharges the cash back will be in fraction of a paise, making further recharges impossible. Also the total recharge done after 14 recharges amounts to 199.99.
