If 2 n can exactly divide p! then the value of n which is not possible :
a. 43 b. 44 c. 45 d. None of these

• ans. 45
  
  If P = 2 then n=1
  P >=4 then n=3
  p>=6 then n=4
  p>= 8 then n=7
  p>=10 then n = 8
  p>=12 then n=10
  
  Hope you got the sequence!!! 1, 3, 4, 7,
  8,10, 11, 14
  15,17,18,21
  
  43, 44, 46, 48

• in this 2 n , here it is 2^n for which i gave solution
  2^n is correct question

• also, if it is 2n then option d. none of these is correct b/c if p!/2n i.e check by optins :
  for 43; 43!/86 completely
  for 44; 11!/88 completely
  for 45; 9!/90 completely
  so option is (d)
