25%

Answer 2

How come?

Answer 3

its 20 percent

Answer 4

Prove it.

Answer 5

ok so what is 25% of 80?

Answer 6

20,right?

Answer 7

let x be price of television
decrease in price=20/100*x=x/5
current price of television =x-x/5=4x/5
for this should be equal to x say k should be added
implies 4x/5+k=x
then k=x/5
i.e, 20%

Answer 8

my mistake its 25 percent
iwil prove

Answer 9

Let the original price be 100
after 20% decrease it becomes 80
now to again make it 100(the original price) we need to add 20 to it
thus the percentage increase will be given as (20/80)*100
hence it gives 25% so the price should be increased by 25%
