Which of the following pairs of integers have reciprocals whose sum is either less than \(\frac{1}{3}\) or greater than \(\frac{1}{2}\)?

Indicate \(all\) such pairs.

A. 1 and 14

B. 3 and 12

C. 5 and 10

D. 7 and 8

E. 6 and 8

Show: :: OA
OA in 24h


Here only option b and E donot match the criteria

3 and 12 donot match the criteria because the reciprocal add up to 0.4166 which in not greater than \(\frac{1}{2}\)
and 6 and 8 donot match the criteria because the reciprocal add up to 0.291 which in not greater than \(\frac{1}{2}\) or less than \(\frac{1}{3}\)

Why is 0.291 not less than 1/3=0.3333333

OAs added. A,C,D


I think E should also be included. 1/6+1/8≈0.291 which is less than 1/3 and thus fits the criteria. Please check and/or critique.
