Question 3 The price of a mobile phone is ₹8,250. A GST of 18% is added to the price. Which of the following gives the final price of the phone including the GST? (i) 8250 + 18 (ii) 8250 + 1800 (iii) 8250 + 18/100 (iv) 8250 × 18 (v) 8250 × 1.18 (vi) 8250 + 8250 × 0.18 (vii) 1.8 × 8250Now, Final price = Listed price + Tax (GST) Finding GST Since 18% is added on the price ₹ 8,250 Thus, GST on mobile phone = 18% × Price of mobile phone = 18% × 8,250 = 18/100 × 8,250 = 0.18 × 8,250 Thus, Final price = Listed price + Tax (GST) = 8,250 + 0.18 × 8,250 = 8,250 × (1 + 0.18) = 8,250 × 1.18 Thus, both (v) and (vi) represent the correct calculation.
