If S is the sum of reciprocals of a list of consecutive integers from 55 to 64, inclusive, S is approximately equal to
Choose the correct choice from the following answers.
A) 0.16
B) 0.2
C) 0.3
D) 0.4
E) 0.5

Rationale: we need to find the approximate value of 1 / 55 + 1 / 56 + 1 / 57 + 1 / 58 + 1 / 59 + 1 / 60 + 1 / 61 + 1 / 62 + 1 / 63 + 1 / 64 . now , the sum of these 10 terms will be very close to 10 times 1 / 60 , which is 0.016 * 10 = 0.16 . answer : a .
Answer: A
