A) \[5\frac{1}{10}\]
B) \[2\frac{1}{18}\]
C) \[3\frac{1}{6}\]
D) \[3\frac{3}{10}\]
Correct Answer: A
Solution :
\[\because \] \[\frac{1}{2}-\frac{1}{4}+\frac{1}{5}-\frac{1}{6}\] \[\frac{30-15+12-10}{60}=\frac{17}{60}\] And \[\frac{2}{5}-\frac{5}{9}+\frac{3}{5}-\frac{7}{18}\] \[=1-\frac{10+7}{18}=1-\frac{17}{18}=\frac{1}{18}\] Required result \[=\frac{17}{60}\times 18=\frac{51}{10}=5\frac{1}{10}\]You need to login to perform this action.
