Step 1: Given data.
TDS deducted = Rs. 3,17,910
We need to find his total income.
Step 2: Assume income structure.
Let Madan’s income = Rs. (5,00,000 + x)
– First Rs. 1,60,000: Nil tax (as per slab for individuals).
– Next Rs. 1,40,000 (1,60,001 – 3,00,000): taxed at 10% = Rs. 14,000
– Next Rs. 2,00,000 (3,00,001 – 5,00,000): taxed at 20% = Rs. 40,000
So, up to Rs. 5,00,000 → Tax = Rs. 54,000
Step 3: For remaining income (x).
Income above Rs. 5,00,000 is taxed at 30%.
So, additional tax = 0.3x
Total base tax = 0.3x + 54,000
Step 4: Add Education Cess.
Including 3% cess:
\[
\text{Tax payable} = 1.03 \times (0.3x + 54,000)
\]
Step 5: Use given condition.
We know tax = Rs. 3,17,910
\[
3,17,910 = 1.03 \times (0.3x + 54,000)
\]
\[
\Rightarrow 0.3x + 54,000 = \frac{3,17,910}{1.03}
\]
\[
= 3,08,650
\]
\[
\Rightarrow 0.3x = 2,54,650 \quad \Rightarrow x = 8,48,835
\]
Step 6: Compute total income.
Total income = Rs. 5,00,000 + Rs. 8,48,835 = Rs. 13,48,835
Final Answer:
\[
\boxed{13,48,835}
\]
