Kamal went to a shop and bought things worth Tk Out of which 30 paisa went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items?

সঠিক উত্তর: Option C
total=taxable cost+tax free cost + tax so, taxable cost=(25-x-0.3)
now, taxable cost* rate of tax(%)=tax so (25-x-0.3)*6/100=0.3
so,tax free price = ( 20-.3) =17.70 tk
