The cost of a tape-recorder is Rs 10,800

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
