A) Rs. 12000
B) Rs. 24000
C) Rs. 30000
D) Rs. 60000
Correct Answer: B
Solution :
Let the monthly incomes of A and B be Rs. 4x and Rs. 3x respectively and their expenditures be Rs. 3y and Rs. 2y respectively. \[\therefore \] \[4x-3y=6000\] And \[3x-2y=6000\] \[\Rightarrow \] \[4x-3y=3x-2y\] \[\Rightarrow \] \[x=y\] \[\therefore \] \[4x-3y=6000\] \[\Rightarrow \] \[x=6000\] \[\Rightarrow \] A's monthly income = 4x = Rs. 24000You need to login to perform this action.
