Income tax calculation, quantitative mathematics

Solution:

We suppose his income is  ;

Income = Rs 100;

instead !

Now we try to find difference by given information.

First Tax=3\frac{1}2{}

New Tax=3\frac{1}{3}

Difference in o;ld and new taxes;

Diffeence = 3\frac{1}{2}-3\frac{1}{3}= \frac{1}{6}

So, we can say that if income is 100 Rs then difference of tax is Rs 1/6

Now we use unitory method to calculate difference of tax !

1-e

Rs 100 = Rs \frac{1}{6} tax

 \Rightarrow Rs 1= Rs \frac{1}{600} tax

 \Rightarrow Rs 2500= Rs \frac{1}{600} \times 2500tax

 \Rightarrow Rs 2500= Rs 46.7 tax
