When sales tax is charged at 10%, for a basic price of Rs.100 the price including sales tax becomes:

Rs 100 + Rs 10 = Rs 110

 

Thus for Rs 110 price + sales tax, the basic price is Rs. 100.

 

Therefore,  for Rs 35640 price + sales tax, the basic price is

= 

 

For Rs. 100 basic price, the price plus 7% sales tax is Rs. 107

 

Therefore, for Rs. 32400 basic price, the price plus 7% sales tax is

=

 

Extra Profit made = Original list price - price with 7% sales tax

= Rs (35640 -  34668)  = Rs. 972
