Two hackers planned to hack a bank account which had debit card pin code in such a format that if a fraction could be made using the first two digits as numerator and last two digits as denominator, then if the numerator of the fraction was increased by 200% and the denominator by 300%, the fraction becomes 12/15. What was the pin of the debit card? 1. 1889 2. 1660 3. 4850 4. 1890 1615 5.
