The price of a TV set will be reduced by 25% and then increased by 25%. Is the current price higher than the original price

Let the original price be X
X-25% X (after price reduction)
=0.75X
(x-25% x) + 25% (x-25% x) (after price increase)
=X-25%X+25%X-0.0625X
=X-0.0625X
=0.9375X
0.9375X>X
Higher than the original price
