| \[\frac{\mathbf{3}}{\mathbf{6}}\mathbf{,}\frac{\mathbf{5}}{\mathbf{10}}\mathbf{,}\frac{\mathbf{9}}{\mathbf{18}}\] |
A) \[\frac{42}{86}\]
B) \[\frac{13}{26}\]
C) \[\frac{62}{124}\]
D) \[\frac{19}{38}\]
Correct Answer: A
Solution :
\[\frac{3}{6}=\frac{1}{2},\frac{5}{10}=\frac{1}{2},\frac{9}{8}=\frac{1}{2}\] The given fractions reduce to \[\frac{1}{2}\] . \[\therefore \] The required fraction is the one which does not reduce to \[\frac{1}{2}\] . Thus, \[\frac{42}{86}\left( \ne \frac{1}{2} \right)\] is the fraction that does not belong to the given set.
