Answer: Option B
Solution(By Examveda Team)
Asha's monthly income := 60% of 78000
$$\eqalign{ & = {\text{Rs}}{\text{. }}\left( {\frac{{60}}{{100}} \times 78000} \right) \cr & {\text{ = Rs}}{\text{. 46800}} \cr} $$
Let Maya's monthly income be Rs. x
Then,
120% of x = 46800
$$\eqalign{ & \Rightarrow {\text{x}} = \left( {\frac{{46800 \times 100}}{{120}}} \right) \cr & \Rightarrow {\text{x}} = 39000 \cr} $$
