Answer 1

20% of 28320=5664 Rupees

So,

computer price= list price-discount

Therefore,

28320-5664=22656 Rupees

Rate of GST=18%

GST=18% of 22656

=18/100 x 22656

GST=4078.08 Rupees

Therefore, the total price of the computer=Discount price+GST

=22656+4078.08

=26734.08 rupees

Therefore, the list price of the computer is 26734.08 rupees

Answer 2

Answer:

List Price = ₹30000 [Frank (Page 12, Sum 19)]

Given:

Price paid = ₹28,320

Discount Percentage = 20%

GST Percentage = 18%

---

Formulae that are going to be used

1. Price paid = Cost Price + Tax

2. Tax = Cost Price x $\frac{R}{100}$  [R here -> GST Percentage]

3. Cost Price = List Price - Discount [List Price is the initial price on the item without tax or anything else]

4. Discount = $\frac{DiscountPercentage}{100}$ x  List Price

---

=> 28,320 = C.P + Tax (Using Formula 1.)

28,320 = C.P + C.P x $\frac{R}{100}$ (Using Formula 2. for tax)

28,320 = C.P + C.P x $\frac{18}{100}$

28,320 = $\frac{100 C.P + 18 C.P}{100}$

28,320 x 100 = 118 C.P

28,32,000 = 118 C.P

₹24,000 = C.P / Cost Price

---

(Using Formula 3)

24,000 = List Price - discount

24,000 = L.P - $\frac{20}{100}$ x L.P (Using Formula 4)

24,000 = $\frac{100 L.P - 20 L.P}{100}$

24,000 x 100 = 80 L.P

$\frac{24,00,000}{80}$ = L.P

₹30,000 = L.P / List Price <- Ans

Hope this helps, (took me more time to format and type than solving smh).
