A)  \[1\frac{5}{4}\] kg                                

B)  \[1\frac{7}{8}\]kg         

C)         \[\frac{5}{4}\] kg        

D)         \[\frac{8}{9}\]kg

Correct Answer: B

Solution :

Weight of     \[=1\frac{5}{6}\]kg = \[\frac{11}{6}\]kg \[\frac{1}{12}\]kg + Weight of     \[=\frac{11}{6}\]kg \[\Rightarrow \]Weight of  \[=\left( \frac{11}{6}-\frac{1}{12} \right)\] kg \[=\frac{7}{4}\] kg Now, \[\frac{1}{8}\]kg + Weight of \[\Rightarrow \] Weight of \[\Rightarrow \] Weight of   \[=\left( \frac{1}{8}+\frac{7}{4} \right)\]kg                         \[=\frac{15}{8}\] kg \[=1\frac{7}{8}\] kg
