Question

Plz solve this sum ​

Answer 1

Answer:

Let the original cost before GST be Rs. x

Cost after GST = Rs. 2240

GST% = 12%

⇒ Cost after GST = Original Cost + GST

⇒ Rs. 2240 = Rs. x + 12% of Rs. x

⇒ Rs. 2240 = Rs. x + 12x/100

⇒ Rs. 2240 = Rs. x + 0.12x

⇒ Rs. 2240 = Rs. 1.12x

⇒ Rs. x = Rs. 2240/1.12

⇒ Rs. x = Rs. 2000

Therefore the original cost of the air cooler before GST was Rs. 2000.
