Answer:
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.
