A laptop costs Rs.27,000. You have to pay 15% extra to purchase an extended warranty of 2 years. What will be the final cost of the laptop if 6% GST must be paid on the whole?

Correct option is C

Given:
Cost price = 27000₹
GST = 6%
Formula Used:
​$$\text{Percentage} = \frac{\text{Value}}{\text{Total Value}} \times 100$$​​
Solution:
For extended warranty of 2 years we get;
CP = 27000 + 27000 × $$\frac{15}{100}$$​​
CP = 31050 ₹
Now 6% GST we get;
CP = 31050 + 31050 × $$\frac 6{100}$$​​
CP = ₹ 32913
