| Direction: What should come in place of the question mark (?) in the following question? |
A) \[2\frac{4}{7}\]
B) \[5\frac{2}{7}\]
C) \[2\frac{1}{3}\]
D) \[\,3\frac{1}{3}\]
E) \[\frac{11}{18}\]
Correct Answer: E
Solution :
\[1+\frac{1}{3}+2+\frac{1}{6}-3-\frac{1}{9}=1-?\] \[\Rightarrow \frac{1}{3}+\frac{1}{6}-\frac{1}{9}=1-?\] \[\Rightarrow \frac{6+3-2}{18}=1-?\] \[\Rightarrow \frac{7}{18}=1-?\] \[\Rightarrow ?=1-\frac{7}{18}\] \[=\frac{18-7}{18}=\frac{11}{18}\]
