Go to the full postSpoiler for what i findfor this solution, depending on how one interpret's

'minimum' amount of questions,i find the answer to exist in the range of37 to 53

the problem is defending on how the brothers will maximize

the amount of questions, you'll find one solution because

they will not reply in random or individual preference but in

a coordinated plan..

1.Maximum to determine the 1/2: F T F T F..T =6 T F F T F..T=6

if 2/3 plays F T F T F..F T F F T F..F2.Maximum to determine the 3/4 :T F F F F F F T F F F T F F F T F F F..T =20

if 4/5 plays T F F F F F F T F F F T F F F T F F F.. F

or 3/4 :T F F F F F T F F F T F F F F T F F F..T =20

if 4/5 plays T F F F F F T F F F T F F F F T F F F..Fbut

3.Maximum to determine the 2/3: T F F F F T F F T F F ..T =12

if 3/4 plays T F F F F T F F T F F.. F

but 1/2 is determined in 3and 4/5 is determined in 9 ... this will not maximize
