as GST

Answer 2

Marked Price = Rs 3500

GST = 12%

Find the Selling Price:

Discount = 20%

Discount = 20% x 3500 = 0.20 x 3500 = Rs 700

Price after discount = 3500 - 700 = Rs 2800

Find the Selling Price including GST:

GST = 12% x Rs 2800 = 0.12 x 2800 = Rs 336

Selling Price including GST = 2800 + 336 = Rs 3136

Find the cost price:

Profit = 10%

Selling Price = 100 + 10 = 110%

Selling Price = Rs 2800

110% = Rs 2800

1% = 2800 ÷ 110 = Rs 280/11

100% = 280/11 x 100 = Rs 2545.45

Answer: (1) Cost Price = Rs 2800 (2) Selling Price including GST = Rs 3136
