A) Rs. 1200
B) Rs. 2400
C) Rs. 4800
D) Rs. 1800
Correct Answer: B
Solution :
Let the incomes of A and B be Rs. 4x and Rs. 3x respectively and their expenses be Rs. 3y and Rs. 2y respectively. Savings of \[A=4x-3y\] and savings of \[B=3x-2y\] Since, the savings of each is same. \[\therefore \] \[4x-3y=3x-2y\] \[\Rightarrow \] \[x=y\] But \[~4x-3y=600\] \[\Rightarrow \] \[4x-3x\text{ }=600~\] \[\Rightarrow \] \[~~x=600\] \[\therefore \] Income of \[A=600\times 4=\text{Rs}\text{.}\,2400\]You need to login to perform this action.
