Detailed Solution

Given that,
Cost with GST included is Rs. 1239.
GST = Rs. 18.
Consider cost without GST =

x

rupees.
Applying the formula,
Cost before GST + GST = Cost with GST.

⇒ x + 18100 × x = 1239

Solving the equation to find

x

⇒ x + 9 x 50 = 1239 ⇒ 50 x + 9 x 50 = 1239 ⇒ 50 x + 9 x = 1239 × 50 ⇒ 59 x = 61950 ⇒ x = 1050

Hence, the price before GST was added is Rs. 1050.
Therefore, option 2 is correct.
