A class of 100 students. 24 of them are girls and 32 are not. Which base am I using?

• if base be b then
  
  100 = 24 + 32
  => 1*b^2 + 0*b^1 + 0 = (2b+4) + (3b+2)
  => b^2 - 5b -6 = 0
  => (b-6)*(b+1) = 0
  => b = -1,6
  base can't negative
  so, b = 6

• 24+32=100
  4+2=6
  6-0=6
  s0 base 6

• (2b+4) + (3b+2) = 1b^2 + 0b + 0 ( b is the base)
  calculating we get
  
  b^2 - 5b - 6 = 0
  so we get 6 as soln

• Base is 6.
  100base6=24base6 + 32 base 6
  36=16+20..

• Let the base be X.
  
  Therefore
  (X*X + X*0 + 0) = (2*X +4) + (3*X + 2)
  X*X = 5*X + 6
  X*X - 5*X -6 = 0
  (X-6)(X+1) = 0
  
  Therefore base is 6
