Question

3.5% of income is taken as tax and 12.5% of the remaining is saved. This leaves 4,053 to spend. What is the income?
​

Answer 1

The income is Rs 4800.

Step-by-step explanation:

The whole income ( x ) is reduced by 3.5 % tax: 100 % - 3.5 % = 96.5% = 0.965

So now we have x * 0.965.

Then 12.5 % of the remaining is saved: 100% - 12.5 % = 87.5 % = 0.875

Now it becomes:

x * 0.965 * 0.875 = 4053

x * 0.844375 = 4053

x = 4053 : 0.844375

x = 4800.
