The mean is calculated as
mean = 
Mean of set A = 
= 
= 266
ratio between means = 7 : 12, then
mean of set B =

Let's do this in Python
day = 1
balance = 0
deposit = 0.01 # first deposit is 1 penny
while balance < 1000000: # execute the loop as long as balance is less than a million dollar
balance += deposit
deposit = deposit * 2 # double the deposit for the next time
day += 1 # add one to day for the next day
print(day) # print out result once loop ends
