The marked price of an article is ₹1,375. If the CGST is charged at a rate of 4%, then the price of the article including GST is:

Given,

Marked price of the article = ₹1,375.

The CGST (Central Goods and Services Tax) = 4%.

As we know that the total GST is composed of CGST and SGST (State Goods and Services Tax) at equal rates, the total GST rate is 8% (4% CGST + 4% SGST).

GST = 8% of marked price of the article

= $\frac{8}{100} \times 1375 = \frac{8 \times 1375}{100} = \frac{11000}{100}$ = ₹110

Final Price = Marked Price + GST Amount

= ₹1,375 + ₹110 = ₹1,485

Hence, option 4 is the correct option.
