Net income = 1.5 - 0.75 + 0 - 0.125 + 2.250 = 2.875

C. 23/8 = 2.875 ---- CORRECT

Hence C is the answer

Hi GMATinsight, VeritasKarishma

According to me net change means (final change - initial change) so it should be.

2.25 - 1.5 = 0.75

I know this is wrong but help me understand this, why this is wrong.

I am just a beginner, Please help me.

Thanks

We need to combine the following, noting that 8 is the common denominator:

3/2 - 3/4 - 1/8 + 9/4

12/8 - 6/8 - 1/8 + 18/8 = 23/8 = 2 7/8

Answer: C

Hi All,

Is there a difference between NET CHANGE and NET CHANGE % ?

So I far I knew that - Net Change% = final value-initial value / initial value * 100

I know , AVERAGE or Arithmetic Mean - sum of observations / number of observations

However ,I am not clear about Net change , the solution seams to a mix of net change % and averages.

Really confused, please help someone.

Net change here means the overall change in prices that is cumulative fall values Throughout the week
