• @astha bcoz it is sated that product of the digit divides the 2 digit number since it is a factor of the 2 digit number..here 4*1 doesnt divide 14..similarly for others also apply the same rule..

• I started my thought process with a 2 digit number.
  
  11=1*1=1 which is a factor of 11
  
  12=1*2=2 which is a factor of 12
  
  15=1*5=5 which is a factor of 15
  
  Similarly, I get 24 and 36.Therefore,My Ans is 5.
