Discounted price = 1200 20% of 1200 .:: Total price of two items
= 1200 - 240 = (360 + 180) = 540
=7960 GST = 18%
CGST = SGST = 9°% of ? 540
Now, SGST = -GST =48.60

18
d =e= 1,680 So, (x - 10% of x) + (r10% of x) 100 =5,310
and Total amount = Total cost + CGST + SGST

For the first item, 18. (a) 11-11%

Discount = Nil Explanation :
Discounted price =Cost price - 200 Tax paid by shopkeeper to the State
GST rate = 10% Government
IGST = 10% of 200=20 = Output SGST - Input SGST
Total amount = 200 + 20 ...(i)

Let, the rate of discount be r%
(ii) For the trader : :. For the shopkeeper,
Cost of the article =20,000 Cost price =9000 - r% of 9000
(:. S.P. of distributor = C.P. of trader]
Tax paid = 10% of 20,000 =9000-x9000
100
=2,000
Selling price of the article = 22,000
=7 (9000 - 90x).
Since. the sales are intra-state,
Tax charged = 10% of 22,000 Input SGST = 6% of (9000-90z)
10x 22,000 6
=2,200 =
(9000-)-90x)
100 100
:.GST paid by the trader =Tax recovered on sale
- Tax paid on purchase B (9000 - 90r) =?540
=2,200 - 2,000
=200 Ans. Selling price =?9000.
