In a landlocked country named Afjanistan, there are only two banks namely B1 and B2. On fixed deposits, B1 pays interest in the form of simple interest at the rate of 10% and B2 pays interest in the form of compound interest, compounded annually, at the same rate. A man deposits 12000 Euros in B1 and withdraws the amount generated at the end of the year and deposits it in B2. At the end of the second year, he withdraws the amount from B2 and deposits it in B1. At the end of the third year, he withdraws the amount from B1 and deposits it in B2. He continues with this strategy. After a minimum of how many years (approximately) will he get an amount which is more than 20400 Euros?
