Question

There are twice as many people in the household, but your income has doubled. Is your new tax liability salbutamol twice as much as when you were single, more than twice as much, or less than twice as much?

Answer 1

twice as much as when you were single

Explanation:

tax liability is calculated from subtracting all expenses from income. Assuming expenses also double, subtracting all expenses from income will result in tax liability twice as much as when you were single

Income initially= x

Income after increase= 2x

expenses initially= y

expenses after increase= 2x

tax liabiltiy initially= x-y

tax liabiltiy after increment= 2x-2y= 2(x-y)= 2× tax liability initially
