Question

An item costs $64. The price is increased by 10%, then reduced by 10%. Is the final price equal to the original price? Explain.

Answer 1

CP = $64

CP when increased 10% = 64 x 110/100 = 70.40

Final CP when reduced by 10% = 70.40 x 90/100 = $ 63.36

Final price is not equal original price
