Question

A person earns $25000 per month and pays 9000 income tax per year. The government increased income tax by 0.5% per month and his monthly earning was increased $11000. How much more income tax will he pay per month.

Answer 1

The person will pay $ 510 more as income tax per month .

Explanation:

Given as :

The monthly income of person = $ 25000

The amount paid as income tax per year =$ 9000

So,The amount paid as income tax per month =$
`(9000)/(12)` = $750

Or, x% is the income tax of the monthly income

I.e x % of 25000 = 750

∴ x % =
`(750)/(25000)`

Or, x =
`(750)/(25000)` × 100

I.e x = 3 %

Now, since the income tax is increase by 0.5 % per month

So, x' = 3 % + 0.5 % = 3.5 %

And The monthly income increase by $ 11000

I.e New monthly income = $ 25000 + $ 11000 = $ 36000

Now, The income tax which the person pay now is 3.5 % of $ 36000

i.e The income tax which the person pay now = 0.035×36000 = 1260 per month

so, The income tax which the person pay now as per year = 1260 × 12 = $ 15,120

∴ The increase income tax per month = $ 1260 - $ 750 = $ 510

Hence The person will pay $ 510 more as income tax per month . Answer
