An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The Inland Revenue Department (IRD) administers income tax.
Assuming no social security tax applies.
Calculate annual income: A nn u a l I n co m e = 14 × 48 , 000 = R s 672 , 000 .
Calculate total income tax: T o t a l T a x = R s 22 , 200 .
R s 22 , 200
Explanation
Understanding the Problem Let's break down this income tax problem step by step! First, we need to identify the government office responsible for administering income tax. Then, we'll calculate Supriya's annual income and determine the income tax she needs to pay based on the provided tax slabs.
Identifying the Responsible Office a) The government office responsible for the administration of income tax is the Inland Revenue Department (IRD).
Social Security Tax b) The question asks about social security tax. However, there is no information about social security tax in the problem. Therefore, we will assume that no social security tax is applied in this case.
Calculating Annual Income c) Now, let's calculate Supriya's annual income. Her monthly salary is Rs 48,000, and her annual income is 14 times her monthly salary. So, A nn u a l I n co m e = 14 × 48 , 000 = R s 672 , 000
Understanding Tax Slabs Next, we need to determine the income tax she should pay based on the given tax slabs. Here's how we'll break it down:
Slab 1: Up to Rs 500,000, the tax rate is 1%.
Slab 2: From Rs 500,000 to Rs 700,000, the tax rate is 10%.
Slab 3: From Rs 700,000 to Rs 1,000,000, the tax rate is 20%.
Slab 4: From Rs 1,000,000 to Rs 2,000,000, the tax rate is 30%.
Slab 5: Above Rs 2,000,000, the tax rate is 36%.
Calculating Tax for Each Slab Now, let's calculate the tax for each slab:
Slab 1: Income up to Rs 500,000 T a x 1 = 0.01 × 500 , 000 = R s 5 , 000
Slab 2: Income between Rs 500,000 and Rs 700,000. Supriya's income in this slab is Rs 672,000 - Rs 500,000 = Rs 172,000. T a x 2 = 0.10 × 172 , 000 = R s 17 , 200
Slab 3: Income between Rs 700,000 and Rs 1,000,000. Since Supriya's annual income is Rs 672,000, she doesn't have any income in this slab. Therefore, the tax is Rs 0. T a x 3 = 0
Slab 4: Income between Rs 1,000,000 and Rs 2,000,000. Since Supriya's annual income is Rs 672,000, she doesn't have any income in this slab. Therefore, the tax is Rs 0. T a x 4 = 0
Slab 5: Income above Rs 2,000,000. Since Supriya's annual income is Rs 672,000, she doesn't have any income in this slab. Therefore, the tax is Rs 0. T a x 5 = 0
Calculating Total Income Tax Finally, let's calculate the total income tax: T o t a l T a x = T a x 1 + T a x 2 + T a x 3 + T a x 4 + T a x 5 = 5 , 000 + 17 , 200 + 0 + 0 + 0 = R s 22 , 200 Therefore, Supriya should pay Rs 22,200 in income tax for the year.
Final Answer In summary, the Inland Revenue Department (IRD) is responsible for income tax administration. Supriya does not need to pay social security tax (based on the problem's assumptions), and she should pay Rs 22,200 in income tax for the year.
Examples
Understanding income tax calculation is crucial for personal finance. For instance, imagine you are planning your annual budget and need to estimate how much tax you will owe. By understanding the tax slabs and how they apply to your income, you can accurately forecast your tax liability and plan your expenses accordingly. This knowledge also helps in making informed decisions about investments and savings to optimize your tax payments.
A device delivering a current of 15.0 A for 30 seconds results in a flow of approximately 2.81 billion billion electrons. This is calculated by first determining the total charge and then finding the number of electrons using the charge of a single electron. Such calculations illustrate the relationship between current and the flow of charge in electric circuits.
