Let Original price be O
Saturday price = 0.8 x O
Monday price = 1.P x 0.8x O
Monday price is 20 percent higher than original.price
So 1.P x 0.8 X O = 1.2 x O
1.P = 1.5
Hence P = 50 %

Let original cost price be x
On Saturday Price is=x-.2x=0.8x
On monday,Price is increased by p%=0.8x+p%of 0.8x
this is equal to x+.2x=1.2x

0.8x+0.8px/100=1.2x
0.8x(1+p/100)=1.2x
1+p/100=3/2
p/100=1/2
p=50%
