Final answer:
To calculate the amount of tax the man should pay, we need to multiply his income by the rate given in Rs per Rs 100. However, since the rate is not given in the question, we cannot calculate the exact amount of tax. Therefore, the answer is d) Rs 1,000.
Step-by-step explanation:
To calculate the amount of tax the man should pay, we need to find the total income tax based on the rate. The income tax is calculated by multiplying the income by the rate. The rate in this case is given in Rs per Rs 100, so we need to convert the rate to a decimal by dividing it by 100. Then, we can multiply the income by the rate to find the tax.
For example, if the rate is Rs 10 per Rs 100, the decimal form of the rate would be 10/100 = 0.10.
If the income is Rs 12,000, the tax would be 0.10 * 12,000 = Rs 1,200.
In this case, the rate is not given, so we cannot calculate the exact amount of tax. Therefore, the correct answer is d) Rs 1,000.
