27 is the right ans
because the director called 3 band members
and
each 3 band members calls three other band members according to this it becomes 3×3= 9
and now again this 9 band members called 3 band members each of them so according to this it becomes 9×3=27
Jyotimodi:

its 40 i got it right

first you have 3 then those 3 brought 3 more each then those brought 3 more each which is 3+3+3+3+3+3+3+3+3+3+3+3+3 which is 39 then add the band teacher which is 40

48 will be right ans
