1. Kamal went to a shop and bought things worth Tk 25, out of which 30 pasa went on sales tax on taxable purchases. If the tax rate was 6%, then what was the cost of the tax free items?

  • A. Tk 15
  • B. Tk 15
  • C. Tk 15
  • D. Tk 15

Answer: Option C

Explanation:

25 TK এর মধ্যে 30 paisa tax.তাহলে original purchase হয়ছে( 25 - .30) বা 24.7 টাকায় যদি এর মধ্যে x টাকার হয় tax free item তবে প্রশ্নমতে বাকি জিনিসের উপর 6% ট্যাক্স।

(24.7 - x) × o.o6 = 0.30

1.482 - 0.06x = 0.30

1.482 - 0.30 = 0.06x

0.06x = 1.182

x = 19.70
