Step 1: Calculate the insured value of the house.
The house is valued at INR 8,00,000 and is insured for 75% of its value.
\[ \text{Insured Value} = 8,00,000 \times 75% = 8,00,000 \times \frac{75}{100} = \text{INR } 6,00,000 \]
Step 2: Calculate the premium paid.
The rate of premium is 0.80% of the insured value.
\[ \text{Premium} = 6,00,000 \times 0.80% = 6,00,000 \times \frac{0.80}{100} = 6,000 \times 0.8 = \text{INR } 4,800 \]
Step 3: Calculate the agent's commission.
The agent's commission is 9% of the premium.
\[ \text{Agent's Commission} = 4,800 \times 9% = 4,800 \times \frac{9}{100} = 48 \times 9 = \text{INR } 432 \]
So, the premium paid is INR 4,800 and the agent's commission is INR 432.
