Which of the following venn-diagram correctly represents indoor games, table tennis and chess?    

A)                    

B)

C)         

D)

Correct Answer: C

Solution :

Chess and Table Tennis are entirely different. But both are indoor games. Let there be (x+1) members. Then, Father's share \[\frac{1}{4},\] share of each other member \[=\frac{3}{4x}\] \[\therefore \] \[3\left( \frac{3}{4x} \right)=\frac{1}{4}\] \[\Rightarrow \] \[4x=36\Leftrightarrow x=9\] Hence, total number of family members =10
