Answer 1

Let monthly income of Komal and Asha be 4x and 3x

Also, let monthly expenses of Komal and Asha be 3y and 2y.

Now,    4x – 3y = 600               ......(i)

           3x – 2y = 600                 .....(ii)

Solving (i) and (ii), x = 600 and y = 600

∴ Total monthly income = (4 + 3)(600) = Rs.4200

this is ur answer.....☺️☺️
