MRP = Rs. 12,000, Discount % = 30%, GST = 18%
Discount =
Selling price (discounted value) =
CGST =
SGST =
IGST =
Amount of Bill =
Ans: MRP = Rs. 12,000, Discount % = 30%, GST = 18%
Discount = 30% of 12,000 =
Selling price (discounted value) = 12000 – 3600 = Rs. 8400
CGST = 9% of 8400 = Rs. 756
SGST = 9% of 8400 = Rs. 756
IGST = 0
Amount of Bill = Selling price + CGST + SGST = 8400 + 756 + 756 = Rs. 9912
Que-2: For the following transaction from Delhi to Jaipur, fill in the blanks to find the amount of bill :
MRP = Rs. 50,000, Discount % = 20%, GST = 28%

CGST =
SGST =
IGST =
Amount of Bill =
Ans:
MRP = Rs. 50,000, Discount % = 20%, GST = 28%
Discount = 20% of 50,000 =

CGST = 0
SGST = 0
IGST = 28% of 40,000 =
Amount of Bill = Selling price + IGST = 40,000 + 11,200 = Rs. 51,200
