The salary payment option in Opu’s office is very peculiar. He isn’t paid anything for his first day job, on the $2^{nd}$ day he receives $1$ taka. And then from the day onwards, he receives the sum of the previous day’s salary. How many days will Opu need to do his job for receiving $10,000$ tk in total from the office?
