If e is an even integer and e/18 is an odd integer, which of the following is NOT an even integer? Choose the correct choice from the following answers:	A) (e^2)/54	B) (e^2)/12	C) (e^2)/9	D) (e^2)/6	E) (e^2)/2
since e is an even integer and e/18 is an odd integer. thus maximum power of 2 in a is one. why ?? because if the power of 2 in the expression has been 2 or greater, then the e/18 must have been an even integer. (18=2*3^2. as 18 contain only one 2 in the expression)   now, any expression in which we have 4 at the denominator will be odd. out of the given options only 12 is a multiple of 4. hence answer should be (e^2)/12
