A) Rs. 450
B) Rs. 500
C) Rs. 600
D) Rs. 750
Correct Answer: C
Solution :
Let the incomes of A and B are Rs. 4x and Rs. 3x and their expenditure are Rs. 3y and Rs. 2y respectively, \[\therefore \] \[4x-3y=600\] ...(i) and \[3x-2y=600\] ...(ii) On solving Eqs. (i) and (ii), we get \[x=600,\] \[y=600\] \[\therefore \] Incomes of \[A=Rs.\,4x=Rs.\,2400\] and income of B \[=Rs.\,3x=Rs.\,1800\] \[\therefore \] Required difference \[=Rs.\,600\]You need to login to perform this action.
