indeed, the wording is a little bit confusing..started doing with algebra..but then said F.. it, let's try the numbers:
started with 160, did not provide the necessary outcome.
then picked 40
40*2 = 80 after 1st round, he gave 1/4 of 40 or 10, thus, he remained with 70
doubled, now he has 140, 10 gave to his friend, remained with 130
doubled, 260, minus 10, remains with 250
now,
40*2-20 = 60
double - 120 , gave 20, remained 100
double, 200, gave 20, remained 180
if we know for sure that he would have had 70 less RS, then 40 definitely works.
