Monthly incomes of A and B are in the ratio of 4 : 3 and their expenses bear the ratio 3 : 2. Each of them saves Rs. 6,000 at the end of the month, then the monthly income of A is
Solution
Let's say monthly incomes of A and B are $$4x$$ and $$3x$$.
and expenses are $$3y$$ and $$2y$$.
Savings will be $$4x-3y$$ and $$3x-2y$$ which is equal.
Hence $$4x-3y$$ = $$3x-2y$$ or $$x$$ = $$y$$
So $$4x-3x$$ = 6000Â
$$x$$ = 6000
Monthly income of A will be 24000
