B. Rs. 60000
C. Rs. 90000
D. Rs. 120000
Answer: Option C
Solution(By Examveda Team)
$$\frac{{{\text{Monthly income of family A}}}}{{{\text{Monthly income of family B}}}}$$ $$ = \frac{{{\text{Area of square A}}}}{{{\text{Area of square B}}}}$$$$\eqalign{ & \Rightarrow \frac{{40000}}{x} = \frac{{{2^2}}}{{{3^2}}} \cr & \Rightarrow x = \left( {\frac{{40000 \times 9}}{4}} \right) \cr & \Rightarrow x = 90000 \cr} $$
