Soppy I have got less time ans that time ,Now i will explain how 2) 36 s the ans
the ratio is 5:3, which is = 20:12; 20+12 = 32(opt 4)                 now 5:3 is also = 25:15 ;  25+15 = 40 (opt 1)                  5:3 = 35:21 ; 35+21 = 56(opt3)   
but only 36 is not possible , therefore the answer is 36 i.e, 36 can not be the number of students
