n is a positive even integer. [#permalink]

n + 1 and 2n - 1 both are odd expressions so its remainder can never be zero.
So A is greater

Re: n is a positive even integer. [#permalink]

Fairly straightforward.
We can try out some numbers starting with 0 (Lowest possible even number)
we have (0+1)(2*0-1)=(1)(1)
Which gives a remainder of 1.
Recall that the unit digit is the remainder when divided by 10 hence lowest possible reminder = 1 > 0

Answer A

simplify the equation = 2n^2+3n+1
as n = even positive integer, taking n = 2 and 4(take 2 cases just to make sure the answer is correct)
n = 2
15/10 = rem is 5
n = 4
45/10 = rem is 5

hence, QA>QB
