E and F represent two distinct digits. If the number 457E89F is divisible by 36, what is the value of (E+F)?	Choose the correct choice from the following options
A) a) 9
B) b) 3
C) c) 12
D) d) 6
E) e) 10
A no. divisible by 36 means it is div by 49 .   to be div by 4 last 2 digits to be multiple of 4 So, F could be either 2 or 6 only   similarly for a number to be div by 9 its sum must be multiple of 9 first. filtering we find E could be either 1,4,7 only.   To be divisible by 9 only 1 works .(if we choose f=6 then E have to be 6 but as per condition EF are distinct) So   E=1   F=2   Ans:- 3.b) 3
