N be a number,the 2,3 and 5 base notations u get last digit is 1.and two out of three the leading digit is 1. N is equal to  Pick.
A) 31  B) 63  C) 74  D) 91  E) 98
number shuld be in format of 2k+1,3k+1,5k+1   so take lcm of 2 3 5 we get 30k+1   so it may be 31 or 91   but in case of 31 leading digit of all 3 case is one   31 base2 = 11111   31 base3 = 1011   31 base5 = 111   so ans is 91   ANSWER:91
