@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..

Tejasvi Kumar  (6 years ago)

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.
