Hello all,
I started studying for the GMAT last week and realized that I forgot everything in Math. I am having hard time understanding the following question from the OG Math Problem Solving Practice Question number 80.
M is the sum of the reciprocals of the consecutive integers from 201 - 300, inclusive. Which of the following is true?
A. 1/3 <M < 1/2
B. 1/5 <M < 1/3
C. 1/7 <M < 1/5
D. 1/9 <M < 1/7
E. 1/12 <M < 1/9
The OG explains the solution process and says that the right answer is A. But after many times of reading the solution over and over again, I do not see reason why the right answer is A.
Please help!
Thank you
