given n>1. we know that n+1 is a +ve number hence, we can multiply both sides by n+1 we get,

Qty A
n + n+1 = 2n +1

Qty B
n+1 - 1 = n

Subtracting n from both sides we get,
Qty A = n+1
Qty B = 0


Subtracting 1 to both sides we get,
Qty A = n
Qty B = -1


Since Qty A is greater than 1; Qty A > Qty B

We can also solve this question by applying some number sense

Given:
Quantity A: n/(n+1) + 1
Quantity B: 1 - 1/(n+1)

Since we're told that n > 1, we know that n is POSITIVE
So, n/(n+1) = POSITIVE/(POSITIVE + 1) = POSITIVE/POSITIVE = POSITIVE

Likewise, 1/(n+1) = 1/(POSITIVE + 1) = POSITIVE/POSITIVE = POSITIVE

So, our two quantities become:
Quantity A: POSITIVE + 1
Quantity B: 1 - POSITIVE

Let's apply some number sense to get:
Quantity A: some number that's greater than 1
Quantity B: some number that's less than 1

Answer: A
