Question

The monthly income of a family is Rs. 50000. The ratio of the expenditure and saving is 4:1. Find the amount of expenditure and saving. ​

Answer 1

Explanation:

If the ratio of expenditure and saving is 4:1, it means that for every 4 units of expenditure, there is 1 unit of saving.

Let's call the expenditure "E" and the saving "S".

We know that the monthly income is Rs. 50000 and the ratio of expenditure and saving is 4:1.

So, we can set up the following proportion:

E/S = 4/1

We know that E+S = 50000, since the income is equal to the sum of expenditure and saving.

So, we can use this equation to find the value of E and S.

We can first solve for E in terms of S:

E = (4/5)S

We can then substitute this equation into the equation E+S = 50000 to find the value of S:

(4/5)S + S = 50000

Solving for S, we get:

S = (50000/(4+1)) = 50000/5 = 10000

Now that we know the value of S, we can use the proportion E/S = 4/1 to find the value of E:

E = 4 * S = 4 * 10000 = 40000

So, the expenditure of the family is Rs. 40000 and the saving is Rs. 10000.
