Question

a watch was bought for rs 2700 including 8% GST find its price before the GST was added​

Answer 1

2700-8/100=2484 Rs.

answer is 2484.

Answer 2

Given,

The final price of the watch including GST = Rs. 2700

GST percentage = 8%

To find,

The price before the GST addition.

Solution,

We can easily solve this mathematical problem by using the following mathematical process.

Let, the price of the watch excluding GST = Rs. x

(Assume x as a variable to do the further mathematical calculations.)

GST amount = x × 8/100 = Rs. 2x/25

Final price = x + 2x/25 = Rs. 27x/25

According to the data mentioned in the question,

27x/25 =2700

x = 2700 × 25/27

x = 2500

Hence, the price before the GST addition is Rs. 2500
