Marcelo deposits a check for the same amount each month. He adds 65% of this amount into an account for his older son and 35% of this amount into an account for his younger daughter. Last month, the bank accidentally added 65% of the check to his daughter’s account and 35% to his son’s account. What percentage of this month’s check should the bank add to his son’s account so that his son’s account has 65% of the overall amount deposited over this month and last month?
