Question:
The cost of a tape-recorder is Rs 10,800 inclusive of sales tax charged at 8%. The price of the tape-recorder before sales tax was charged is _____.
Solution:
Rs.10000
Explanation: Cost of tape recorder = Rs.10800
Say, the cost before including the tax = x
Therefore,
x + x×(8/100) = 10800
(100x+8x)/100 = 10800
108x = 1080000
x = 10000
