Answer:
Anil and Mukesh resp.
incomes =6x,5x
annual expenses =3y,2y
savings=Rs.3000,Rs.4000
income-expense=saving
6x-3y=3000___(1)
5×-2y=4000___(2)
eqn(1)×5
eqn(2)×6
30x-15y=15000
30x-12y=24000
subtracting above both equations
30x-15y-(30x-12y)=15000-24000
30x-15y-30x+12y=-9000
-3y=-9000
y=9000/3
y=3000
x=2000
Annual income of Anil =6×2000=12000
