A washing machine is sold for Rs 15,912 inclusive of GST. The cost of the washing machine, excluding GST, would be when the rate of GST is 17%?

15200

13600

14200

None of these

Let's say the cost price (CP) of the washing machine is x.

Given that the GST rate is 17%, the selling price (SP) would be:

SP = x + 0.17x

SP = 1.17x

Given that SP = Rs 15,912:

1.17x = 15912

x = 15912 / 1.17

x = 13600
