Rs .460/-
loss=20/-
%loss=5%
therefore 15% is the actual loss for 400/-
therefore 60/- is the actual loss
therefore 460/- is the actual price

It should be 500. (500-400)/500=20% loss, (500-380)/500=24%, (24%-20%)/20%=20%.

It should be 425.
Bcz
(x-400)-(400-380)/x-400 = 20%

(x-400)-20/x-400=20/100

x-420/x-400 = 20/100

20(x-400)=(x-420)100

20x-8000 = 100x-42000

80x = 34000

x = 425.
